In this video, I explained why not many people know about tetration because it is of little relevance to every day numbers Buy the t-shirt here shorturl.at/HNUX1
2 is also the only number for which a+a = a·a = a^a = a↑↑a = a↑↑↑a and so on, no matter how many times you iterate this process. The result is always 4.
so if a = b = 2, then for any n greater than 0, the hyperoperation associated with n in the form a (whatever hyperoperation you are using) b will always compute to be 2? ok
@@ChraO_o the concept i understood is that it is repeated exponents. for instance, we know exponent is repeated multiplication, so by looking into the consept of tetration, it can be seen that it's vasically repeated exponent

Thank you so much ! I was kinda exhausted learning the old things.... this new thing kinda lifted up my spirits !! Hope you'll continue presenting these new concepts !! 😃
Nah i watched your eigenvalue video for my calc 3 class and found this gem, ngl you might be one of the few passionate teachers on youtube, u genuinely have fun with maths and that's i think is rare nowadays, hats off to you gentlemen.
Parenthesis first, so 2 multiplied by itself 4 times = 16, so then 16 multiplied by (16 multiplied by itself by 16) so 16x16x16.. 16 times which = 1.8446744e+19 (so big my calculator can’t handle it). 16 *MULTIPLIED BY ITSELF THIS NUMBER OF TIMES* 1.8446744e+19
16. This is because "2 tetrated to 3" means we need 2 "floors" of exponents. The "ground floor" is also part of the 3, this is why we only have 2 floors above ground level and not 3. Like this: 2^(2^2) = 2^(4) = 16. If it was 2 tetrated to 4 it would be: 2^(2^(2^2)) = 2^(2^(4)) = 2^(16) = 65536. It quickly gets very big.
Bruce Lee also said that! EDIT: Shoot, what he actually said was "An intelligent mind is one which is constantly learning, never concluding - styles and patterns have come to conclusion, therefore they [have] ceased to be intelligent." Probably still makes sense in this context..
I have studied math at uni for 5 years and never come across the definition this. As you said it is probably because it is a bit useless (as ³10 is basically infinity). Very interesting and a nugget of knowledge. Thanks!
During the 10^3 bit, it occured to me that in my math experience, I lost the meaning of some of these values. 100 to 1000 is huge, but I really do forget the scale of numbers sometimes.
I guess it always depends on what the numbers mean. 100 atoms vs 1000 atoms is next to nothing. 100 houses vs 1000 houses is very big. 100 planets vs 1000 planets is unfathomably large.
Well then think about the 1-2-4-8-16-32.... series. Do you know that you only need to add them together in order to get every other number in between? And you never need to repeat 1 of them.... that's why/how computers exist/work basically. Think about how many numbers there are between 2-4 and 128-256... and so on 😮. It works INFINITELY. It means the x2 series gives birth to all numbers as well as the 1+1 series does. Its just disturbing how perfect and efficient it is to derive all numbers from the 1x2... series...(binary code...bits...bytes...and so on). The universe is just amazing when you think about it sometimes. Division and doubling is at the very core of each of its seemingly random processes... all of em even sound, light and matter... constants.. ect.
Vsauce did an analysis on this. Our brains think logarithmically (e.g. 1, 10, 100, 1000, ...), not cumulatively (1, 2, 3, 4, ...). It allows us to think in scales and relativity of the massive sizes of galaxies to the invisibly small sizes of atoms.
@Obi1Classic yup we often underestimate our brains. We can easily think of planets and galaxies or atoms and electrons. We just need to discuss them in 'peer to peer' contexts of other objects that are just as large within an order of magnitude or so. What is HARD to imagine is not the size of our entire planet or even the distance to the closest star, but the ratio between the 2. That is going to surprise you, and it's hard to mentally model it. If you do you're probably needing a second map, that is another layer of abstraction.

How many hours did you study these things in school? Knowing what something means is different than understanding it and being able to use the knowledge.
@@pannumonThe only reason early math difficult is because it involves mostly memorization but once you've learned the fundamentals then math becomes really easy. The majority of college and highschool math was essentially plug numbers into a formula and then hit enter on the calculator.
I was expecting a huge number again, but I think it's 16. According to your explanation it would be written as 2 to the power of 2 to the power of 2. The last two become 4 and that makes 2 to the power of 4 which is 16. Never knew about tetration. Never to old to learn. Thanks
Which is what GOD ALMIGHTY is all about ... inexhaustible knowledge about HIS CREATION ... and it never stops no matter how much HE has taught any of them!
I believe in trying to learn something new each day (and not triva). I am 79 and have never seen this before. If I understand what's going on, then the answer should be 16. Although, I almost convinced myself on 256, but decided I was getting carried away by all the numbers😅. Thank you for the lesson and the knowledge.
Please help me figure out this 🙏 I'm having a seizure: Why is it that 10billion ^ 10 isn't equal the 10^10billion they should be equal because order doesn't matter when doing 10^10^10 right? And yet the former is 1 followed by 100 zeros and the latter is 1 followed by 10billion zeros..
well first off, in 10^10^10 they are all the same number so thats why it doesn't matter. but also, when 10^10B has to multiply by 10, 10 billion times and when we are talking exponentials it gets out of control. 10B^10 is only multiplying by itself 10 times, which is just incomparable. The exponent matters way more than the number you start with, any feasible number to the 10B is gonna be light years bigger than any feasible number to the 10@@Hanible
@@HanibleI don't know if I understood your question correctly (English is not my first language) so I'm just going to talk about the issue of order. There is an order to carry out tetration. I don't know how to explain why, but you always start from top to bottom. (or right to left) Ex: ⁴3= 3^3^3^3 3^3^27 3^7,625, 597, 484, 987 = Big ass number
@@Hanible, they are not equal becos for 10 000,000,000^10 = 10^(10^2) based on law of indices, which is not equal to 10^(10^10). Think about it and you will get an ans. 🙂
@shiva11456 yeah I already know 10B^10=10^(10^2) that's why I said it's 1 followed by 100 zeros... And I noticed they weren't equal that's the whole point, my question is why aren't they equal? I thought order didn't matter when doing a^b^c... but if it matters why does it matter? 🤔
The answer is 16 because 2 to the power of 2 to the power of 2, so you have 3 twos which is why it is called the 3rd titration of 2, it’s kinda like how powered numbers work but it is bigger, turn the multiplications into powers.
@@CatNolaraNo. You did 3^(3*3) which is not how tetration works. In tetration the outermost exponent is in the innermost brack so 3 tetrated to three 3^(3^3) or 3^27 which is ~7.6 trillion
16. 2 is the smallest base of complete numbers to not completely overload our imagenation. Very nice! Really like your video🙏 + very nice code in the end❤
The tetration of 3, denoted as 2↑↑3, is equal to 2^(2^2), which is 2 raised to the power of 2 raised to the power of 2. So, 2 to the tetration of 3 is 16 (2^(2^2) = 2^4 = 16).
I'm so confused by the notation more than anything. Abstract infinities make intuitive sense to me. The way you humans describe them makes my organs hurt.
Trust me it doesn’t work when teaching a class😂 it’s fine for a CZcams video, but when teaching a curriculum it is flawed. I’m currently studying maths, further maths and physics, and one teacher we have for further mathematics has this approach, and he ends up confusing everyone! Like I said, no problem here, as this is just some fun maths, not too complicated but it doesn’t work at a higher level
@@fullsendmountainbiker5844 Yes it does, but at higher levels there is already an expectation of prior knowledge, so some of this can be skipped. Also at higher levels you need to go and bring things back to simple, otherwise you have idiots with so called higher education trying to use Algebraic calculations and rules in basic math using PEMDAS and getting the wrong answer. IE: Confusion, why? because the basics of why are not taught only how and shortcuts. It has to be taught to use the level of math required/needed for the specific situation. Boolean Algebra doesn't apply to everything, but there is a place for it.
@@chrish7336 yes there is obviously an expectation of prior knowledge, but you can’t assume everyone in a class can just work a challenging mathematical concept out themselves. If I could do that I’d be a genius, and I’d have no need for any education. Don’t get me wrong this kind of teaching works for some topics, but not for others
Amazing Video! They don't teach this in school but I had heard of it before, thanks for explaining how it works. "Don't stop learning, those who stop learning have stopped living" Such a moving thought! 🤩
This video was REALLY AMAZING I’m Brazilian so I didn’t understand much, but as mathematics is a universal language it was easy to follow. Your happiness in teaching is contagious, thank you.
basicamente, oq ele ta chamando de "tetration" é vc pegar um número e elevar ele ao mesmo número, que tbm tá elevado a esse número (repetindo isso o número de vezes do "expoente") Exemplo: ³2 = 2²^² = 2⁴ = 16
A generalisation of tetration is Knut's up-arrow notation. It's basically the same concept with the notation 2↑3 for 2³, 2↑↑3 for ³2, but you don't stop there and go with how many arrows you want, for example, 2↑↑↑3 is 2↑↑2↑↑2 which is 2↑↑2↑2=2↑↑4=2↑2↑2↑2=2↑16=2¹⁶=65'536. I really recommend searching about this, especially about Graham's number, which is the biggest number used in a mathematical proof(Edit: apparently not anymore? Couldn't find any proofs, tho. Any information could help Edit in the edit:G64(Graham's number) is still the biggest in a demonstration after further researches). Next to this number, ³10 doesn't seem that big. It looks horrifically tiny, as a matter of fact. Edit: I forgot to say that these operations are, as exponentiation, right-associative. This means that you calculate them from right to left just like you calculate exponentiation from top to bottom.
@@TekExplorerthe caret is only used as a replacement for up arrows when they are not available on the keyboard. On paper or when you have access to them you will tend to use the complete arrow. If you want to verify this information, I found it on Wikipedia on the "Knuth's up-arrows notation" page in the "notation" category
I Love your Way of teaching. And the smile that is on your face showing how excited you are about The Wonder of numbers. If only more teachers taught this way to get students excited about numbers too, it would be amazing. If you are not or were not a school teacher or college professor, you missed your calling.
"If only more teachers ..." being excited is not reproducable very often, meaning a teacher may even only be excited the first time teaching, solution: capture the video and show it to next year's students.
@@anonym-hubI went to a new school were I was assigned to a math teacher who let an audio tape and overhead projector teach the class. That didn't work for me at all. When I transferred to another class it was great because the football coach (about 5'4") and the track coach (about 6'8") had combined their math classes and made it fun as well as educational. Just watching that mismatched pair working together was entertaining. 😂
nah bruv he took 7 minutes for that shit. Its one thing trying to accommodating but assuming the general audience who watches is THIS dumb that they need 7 minutes for it?
I hope this clarifies what I said. 10↑↑3 is written as 1 followed by 10 billion zeros. There is enough space in my house to print out the number with 10 billion zeros. What I meant to say in the video was that if I had to write down all the numbers from 1 to 10↑↑3, there would not be enough space in the known universe to write them all even if every atom is large enough to write on.
You can also evaluate non integer hyper powers like 2^^π NOTE: I use HLog as notation for Hyper Logarithm Another common notation is slog for Super Logarithm Hyper Logarithm (one inverse of Tetration) is repeated Logarithm by definition. Let T=The total number of Logs til the answer ≤ 1 r = the remainder of the last log HLog a(b) = x --> a^^x = b by definition of hyper logarithms x=(T-1)+r By definition of Tetration, a^^x = a^(a^^x-1)… Taking HLoga(z) Given z is not an integer hyper power of a Let HLoga(z) = b+x Given 0 ≤ x ≤ 1 and b=Z z = a^^(b+x) = a^a^^(b-1+x) = a^a^...(b copies)...^a^^x By definition of tetration z = a^a^...(b copies)...^a^x By definition of Hyper Log (Repeated Logarithm) They both equal z thus they equal eachother a^a^...(b copies)...^a^x = a^a^...(b copies)...^a^^x The entire tower cancels via Loga() on both sides, leaving a^x = a^^x Given 0 ≤ x ≤ 1 Therefore a^^x = a^x Given 0 ≤ x ≤ 1 is true by definition. We can solve 2^^π 2^^π = 2^2^^(π-1) = 2^2^2^^(π-2) = 2^2^2^2^^(π-3) 2^^π = 2^2^2^2^(π-3) ≈ 21.596356101 2^2^2^2^^(π-3) = 2^2^2^2^(π-3) ≈ 21.596356101 (Notice you can Log2 both sides and be left with 2^^(π-3) = 2^(π-3). ) We can also check this Log2(21.596356101) ≈ 4.4327160055 --> 1st Log Log2(4.4327160055) ≈ 2.1481909351 --> 2nd Log Log2(2.1481909351) ≈ 1.1031222284 --> 3rd Log Log2(1.1031222284) ≈ 0.1415926536 --> 4th Log, answer ≤ 1 --> r For 2^^x = 21.596356101 x=(T-1)+r, 4 total Logs x=(4-1)+r = 3+r = 3+0.1415926536 = 3.1415926536 ≈ π (obviously. with irrationals there will be possible rounding errors) Thus 2^^π ≈ 21.596356101 is indeed true
Just graduated year 12 with a growing hatred for learning maths due to the brute forced and completely confusing maths curriculum. Watching this video was genuinely interesting, your passionate and excited explanation of tetration that i was pretty sure i would be completely lost on and click off the video, somehow kept my attention and got me really curious to see this through regardless if i understood or not. Just wanted to take a moment to appreciate this video and the interest it somehow sparked within me for maths, even a slight bit. Also that handwriting is pristine. Keep up the good work.
Try derivatives and Laplace Transforms. Even Z transforms are useful when dealing with sample rates from a computer and systems exhibiting weight, velocity and hydraulic dampening. I love math, but yes, it is very difficult to understand.

Never in my life did I think that I would scroll on youtube and actually watch a video where I would hear something, I have never heard in my life. Tysm for sharing!! It was lowkey bussin
Wow I'm glad I found this channel, I really like your style and you for that matter. I personally learned about tetration (and quintation, hexation etc..) when I was taught Knuth's up arrow notation in college as the next step was to take the derivative of a tetratic expression.
When I was in seventh or eighth grade I had already developed a love and admiration for math, one day I was reflecting about it and asked my teacher: "so there's addition, then multiplication, then exponentiation. is there anything that comes after exponentiation?". To which he replied with a simple and final "no. nothing beyond it.". Well I feel really good now to know I was right at that time and that tetration exists.
it's 16... I came across your video while scrolling through CZcams and I'm fixedly attracted to it you gave me a golden knowledge thank you I've never seen this before it really worth a lot!!❤❤❤
When you calculate a tower of exponents, you work from the top down. If you add levels to the LEFT tower, do you have to work from the bottom level to get the first exponent tower, then the second etc.?
Man, I SO wish I had math teachers like you in school. I always loved math but few of my teachers did. Not only do you clearly love the subject, which is transformative when it comes to teaching, but there's just something about the way that you teach that is inherently very engaging, completely independent of the math. I can't put my finger on it, but it's there.
That was fun. I've long thought that the fastest and most compact way to make big numbers was using a number like 9 to the power of 9 to the power of 9 to the power of 9 So Tetration is simply formalizing a syntax for it. In my example, 4(tetration)9 Or in computer syntax from one of the old languages I used, 9^9^9^9
We can extend the concept even farther. Lets say º is tetration and lets say ~ is repeated tetration, then; 2º3 = 2^2^2 2~3 = 2º2º2 = 2º16 = 2^2^2^2^2^2^2^2^2^2^2^2^2^2^2^2 Which is uncomputably large I tried pluging it into wolrfram alpha and best it could do is say it is equal to 10^(10^(10^(10^(10^(10^(10^(10^(10^(10^(10^(10^19727.78040560677)))))))))))
I went down a bit of a rabbit hole and discovered it doesn't stop with tetration. Tetration is a part of these things called hyper operations and is also known as hyper-4. Apparently someone was insane enough to coin a term for hyper-infinity: Circulation
What about the next step of tetration? Like having 2 and 2 be 2 tetrated two times Like 9 (super tetrated) 9 times would be 9 tetrated by 9 tetrated by 9 tetrated by 9 tetrated ... (9 times) lol
I split it up like this = 2^2 is 4, so i then added the remaining “2” exponent, onto the 4, which is 4^2. So 4^2, is 16. I can’t believe i actually learned a math concept from a CZcams video this efficiently. Genuinely a wonderful teacher.
@@ThePrintZone123 you need to explain it better in the vid. All you said was it is a billion for each time you multiple it. So that infers it should have been 8 billion... 2 x 2 is 4 4x 2 is eight that's using the 2 three times.. to get to 16 you have to have another 2. Why is there not a 4 in front of the 2?
I liked when you said "those who have stopped learning are those who have stopped living." It reminded me of my senior quote: "to live is to learn, to learn is to grow, to grow is to live."
16. Not even a big fan of math but this was very relaxing and a great way to explain, I could show a fifth grader this and they'd understand because this video is also disguised as a way to learn exponents too.
It has been a long time since I’ve needed to process information in this way and I didn’t realize how much I missed it. Thank you so much and I will be watching all of your future videos. You are amazing.
16 because ³2 is like writing 2^2^2^2, where the base is used as an exponent, and the 3 in front indicates how many times the exponent is repeated. ³2 written in exponent form would be 2⁴

Teachers who teach with passion or excitement help people grasp the subject. You talked clear and to the point in a way that wasn't condescending loved it subbing now
Tetration is a hyperoperation that involves iterated exponentiation. The notation \( ^n a \) denotes the \( n \)-times iterated exponentiation of \( a \). For example, \( ^3 2 \) means 2 raised to the power of 2, raised to the power of 2. For \( ^3 2 \), this can be calculated as: \[ ^3 2 = 2^{2^2} \] First, solve the innermost exponentiation: \[ 2^2 = 4 \] Then, use this result as the exponent for the base 2: \[ 2^4 = 2 \times 2 \times 2 \times 2 = 16 \] Therefore, \( ^3 2 = 16 \).
Somehow your videos have never come across my feed or my search results before. I really enjoyed everything about this video and yourself. I subbed not only for the aforementioned reason, but the sound of the chalk tapping on the blackboard made this GenXer's heart skip a beat!
2 is also the only number for which a+a = a·a = a^a = a↑↑a = a↑↑↑a and so on, no matter how many times you iterate this process. The result is always 4.
so if a = b = 2, then for any n greater than 0, the hyperoperation associated with n in the form a (whatever hyperoperation you are using) b will always compute to be 2? ok

16. This is because "2 tetrated to 3" means we need 2 "floors" of exponents. The "ground floor" is also part of the 3, this is why we only have 2 floors above ground level and not 3.
Like this: 2^(2^2) = 2^(4) = 16. If it was 2 tetrated to 4 it would be: 2^(2^(2^2)) = 2^(2^(4)) = 2^(16) = 65536.
It quickly gets very big.
Mother fucker dont tell me this is not written by chatGPT, this is very easy to do on your own
I got the same answer!
Damn the 2 tetrated to 4 got me messed up, but think I get it now.
I understand it now, thanks for the explanation!
wouldnt the exponents simply multiply with eachother? 2^2^2^2 (or 2 tetrated to 4) would be 2^(2*2*2)=256 right?
This was awesome! I started over thinking it but instead just remembered how you did it for the 10s. Thank you for some new information!

I have studied math at uni for 5 years and never come across the definition this. As you said it is probably because it is a bit useless (as ³10 is basically infinity). Very interesting and a nugget of knowledge. Thanks!
Maths becomes interesting when it's taught by an enthusiastic teacher like you!!
During the 10^3 bit, it occured to me that in my math experience, I lost the meaning of some of these values. 100 to 1000 is huge, but I really do forget the scale of numbers sometimes.
I guess it always depends on what the numbers mean. 100 atoms vs 1000 atoms is next to nothing. 100 houses vs 1000 houses is very big. 100 planets vs 1000 planets is unfathomably large.
Well then think about the 1-2-4-8-16-32.... series. Do you know that you only need to add them together in order to get every other number in between? And you never need to repeat 1 of them.... that's why/how computers exist/work basically.
Think about how many numbers there are between 2-4 and 128-256... and so on 😮. It works INFINITELY. It means the x2 series gives birth to all numbers as well as the 1+1 series does. Its just disturbing how perfect and efficient it is to derive all numbers from the 1x2... series...(binary code...bits...bytes...and so on). The universe is just amazing when you think about it sometimes. Division and doubling is at the very core of each of its seemingly random processes... all of em even sound, light and matter... constants.. ect.
Vsauce did an analysis on this. Our brains think logarithmically (e.g. 1, 10, 100, 1000, ...), not cumulatively (1, 2, 3, 4, ...). It allows us to think in scales and relativity of the massive sizes of galaxies to the invisibly small sizes of atoms.
@Obi1Classic yup we often underestimate our brains. We can easily think of planets and galaxies or atoms and electrons. We just need to discuss them in 'peer to peer' contexts of other objects that are just as large within an order of magnitude or so.
What is HARD to imagine is not the size of our entire planet or even the distance to the closest star, but the ratio between the 2. That is going to surprise you, and it's hard to mentally model it. If you do you're probably needing a second map, that is another layer of abstraction.

Why is it that 10billion ^ 10 isn't equal the 10^10billion they should be equal because order doesn't matter when doing 10^10^10 right? And yet the former is 1 followed by 100 zeros and the latter is 1 followed by 10billion zeros..
well first off, in 10^10^10 they are all the same number so thats why it doesn't matter. but also, when 10^10B has to multiply by 10, 10 billion times and when we are talking exponentials it gets out of control. 10B^10 is only multiplying by itself 10 times, which is just incomparable.

@@HanibleI don't know if I understood your question correctly (English is not my first language) so I'm just going to talk about the issue of order.
There is an order to carry out tetration. I don't know how to explain why, but you always start from top to bottom. (or right to left)

@shiva11456 yeah I already know 10B^10=10^(10^2) that's why I said it's 1 followed by 100 zeros... And I noticed they weren't equal that's the whole point, my question is why aren't they equal? I thought order didn't matter when doing a^b^c... but if it matters why does it matter? 🤔
The answer is 16 because 2 to the power of 2 to the power of 2, so you have 3 twos which is why it is called the 3rd titration of 2, it’s kinda like how powered numbers work but it is bigger, turn the multiplications into powers.

Trust me it doesn’t work when teaching a class😂 it’s fine for a CZcams video, but when teaching a curriculum it is flawed. I’m currently studying maths, further maths and physics, and one teacher we have for further mathematics has this approach, and he ends up confusing everyone! Like I said, no problem here, as this is just some fun maths, not too complicated but it doesn’t work at a higher level
@@fullsendmountainbiker5844 Yes it does, but at higher levels there is already an expectation of prior knowledge, so some of this can be skipped.
Also at higher levels you need to go and bring things back to simple, otherwise you have idiots with so called higher education trying to use Algebraic calculations and rules in basic math using PEMDAS and getting the wrong answer. IE: Confusion, why? because the basics of why are not taught only how and shortcuts.

basicamente, oq ele ta chamando de "tetration" é vc pegar um número e elevar ele ao mesmo número, que tbm tá elevado a esse número (repetindo isso o número de vezes do "expoente")
Exemplo: ³2 = 2²^² = 2⁴ = 16
A beautiful concept explained in a beautiful way . ❤
The fact that I learnt this in Chemistry lesson, even though it was not part of our course but our sir still generously explained it.
A generalisation of tetration is Knut's up-arrow notation. It's basically the same concept with the notation 2↑3 for 2³, 2↑↑3 for ³2, but you don't stop there and go with how many arrows you want, for example, 2↑↑↑3 is 2↑↑2↑↑2 which is 2↑↑2↑2=2↑↑4=2↑2↑2↑2=2↑16=2¹⁶=65'536. I really recommend searching about this, especially about Graham's number, which is the biggest number used in a mathematical proof(Edit: apparently not anymore? Couldn't find any proofs, tho. Any information could help Edit in the edit:G64(Graham's number) is still the biggest in a demonstration after further researches). Next to this number, ³10 doesn't seem that big. It looks horrifically tiny, as a matter of fact.
Edit: I forgot to say that these operations are, as exponentiation, right-associative. This means that you calculate them from right to left just like you calculate exponentiation from top to bottom.
Not sure where you got "up arrow" from - the character you mean is actually on your keyboard: "^"
@@TekExplorernope, that particular notation uses up arrows, as dictated by the name..
@ He's clearly talking about the lesser-known Knuth's Caret Notation.
@@TekExplorerthe caret is only used as a replacement for up arrows when they are not available on the keyboard. On paper or when you have access to them you will tend to use the complete arrow.

Very nice video, and I like your saying "those who've stopped learning, have stopped living"
I hope this clarifies what I said. 10↑↑3 is written as 1 followed by 10 billion zeros. There is enough space in my house to print out the number with 10 billion zeros. What I meant to say in the video was that if I had to write down all the numbers from 1 to 10↑↑3, there would not be enough space in the known universe to write them all even if every atom is large enough to write on.
i was about to ask about that. it would probably take about 1,000 years to write it, or 2,000 maybe.
no, more like 700 years i think
10↑3 = 1000. As a single arrow is exponentiation. 10↑↑3 is 1 followed by 10 billion zeros.
Really? It maked sense to me in the video now I’m confused
Yeah, I thought that was an error, but just a misinterpretation.
You can also evaluate non integer hyper powers like 2^^π
NOTE: I use HLog as notation for Hyper Logarithm Another common notation is slog for Super Logarithm
Hyper Logarithm (one inverse of Tetration) is repeated Logarithm by definition.
Let T=The total number of Logs til the answer ≤ 1
r = the remainder of the last log
HLog a(b) = x --> a^^x = b
by definition of hyper logarithms x=(T-1)+r
By definition of Tetration, a^^x = a^(a^^x-1)…
Taking HLoga(z) Given z is not an integer hyper power of a
Let HLoga(z) = b+x Given 0 ≤ x ≤ 1 and b=Z
z = a^^(b+x) = a^a^^(b-1+x) = a^a^...(b copies)...^a^^x By definition of tetration
z = a^a^...(b copies)...^a^x By definition of Hyper Log (Repeated Logarithm)
They both equal z thus they equal eachother
a^a^...(b copies)...^a^x = a^a^...(b copies)...^a^^x The entire tower cancels via Loga() on both sides, leaving a^x = a^^x Given 0 ≤ x ≤ 1
Therefore a^^x = a^x Given 0 ≤ x ≤ 1 is true by definition.
We can solve 2^^π
2^^π = 2^2^^(π-1) = 2^2^2^^(π-2) = 2^2^2^2^^(π-3)
2^^π = 2^2^2^2^(π-3) ≈ 21.596356101
2^2^2^2^^(π-3) = 2^2^2^2^(π-3) ≈ 21.596356101 (Notice you can Log2 both sides and be left with 2^^(π-3) = 2^(π-3). )
We can also check this
Log2(21.596356101) ≈ 4.4327160055 --> 1st Log
Log2(4.4327160055) ≈ 2.1481909351 --> 2nd Log
Log2(2.1481909351) ≈ 1.1031222284 --> 3rd Log
Log2(1.1031222284) ≈ 0.1415926536 --> 4th Log, answer ≤ 1 --> r
For 2^^x = 21.596356101 x=(T-1)+r, 4 total Logs
x=(4-1)+r = 3+r = 3+0.1415926536 = 3.1415926536 ≈ π (obviously. with irrationals there will be possible rounding errors)
Thus 2^^π ≈ 21.596356101 is indeed true

Now Tell Googol Tetrate Googol 🙂
Man, I SO wish I had math teachers like you in school. I always loved math but few of my teachers did. Not only do you clearly love the subject, which is transformative when it comes to teaching, but there's just something about the way that you teach that is inherently very engaging, completely independent of the math. I can't put my finger on it, but it's there.
That was fun. I've long thought that the fastest and most compact way to make big numbers was using a number like 9 to the power of 9 to the power of 9 to the power of 9 So Tetration is simply formalizing a syntax for it. In my example, 4(tetration)9 Or in computer syntax from one of the old languages I used, 9^9^9^9
And the number of your base can increase too, so 9(tetration)99 is unimanginably bigger than 9(tetration)9
We can extend the concept even farther. Lets say º is tetration and lets say ~ is repeated tetration, then;
2º3 = 2^2^2
2~3 = 2º2º2 = 2º16 = 2^2^2^2^2^2^2^2^2^2^2^2^2^2^2^2
Which is uncomputably large I tried pluging it into wolrfram alpha and best it could do is say it is equal to 10^(10^(10^(10^(10^(10^(10^(10^(10^(10^(10^(10^19727.78040560677)))))))))))
Then search grahams number hahahah
I went down a bit of a rabbit hole and discovered it doesn't stop with tetration. Tetration is a part of these things called hyper operations and is also known as hyper-4. Apparently someone was insane enough to coin a term for hyper-infinity: Circulation
What about the next step of tetration? Like having 2 and 2 be 2 tetrated two times
Like 9 (super tetrated) 9 times would be 9 tetrated by 9 tetrated by 9 tetrated by 9 tetrated ... (9 times)
lol

It has been a long time since I’ve needed to process information in this way and I didn’t realize how much I missed it. Thank you so much and I will be watching all of your future videos. You are amazing.
16... Thank You so much for teaching us something new❤️
16 because ³2 is like writing 2^2^2^2, where the base is used as an exponent, and the 3 in front indicates how many times the exponent is repeated. ³2 written in exponent form would be 2⁴
Recovering from a burnout, worked in finance. Your vid’s are great to get back into things again! Loooove your positive energy, much respect from 🇳🇱 processor. You are a great teacher!
Teachers who teach with passion or excitement help people grasp the subject. You talked clear and to the point in a way that wasn't condescending loved it subbing now
Tetration is a hyperoperation that involves iterated exponentiation. The notation \( ^n a \) denotes the \( n \)-times iterated exponentiation of \( a \). For example, \( ^3 2 \) means 2 raised to the power of 2, raised to the power of 2.
For \( ^3 2 \), this can be calculated as:
\[ ^3 2 = 2^{2^2} \]
First, solve the innermost exponentiation:
\[ 2^2 = 4 \]
Then, use this result as the exponent for the base 2:
\[ 2^4 = 2 \times 2 \times 2 \times 2 = 16 \]
Therefore, \( ^3 2 = 16 \).
I wish I would’ve known about this in advance chemistry it would’ve made things so much easier and better!
Somehow your videos have never come across my feed or my search results before. I really enjoyed everything about this video and yourself. I subbed not only for the aforementioned reason, but the sound of the chalk tapping on the blackboard made this GenXer's heart skip a beat!
