Simplify a radical expression with variables
VloĆŸit
- Äas pĆidĂĄn 6. 12. 2011
- đ Learn how to simplify the square root of an expression. The square root of an expression is an expression which will multiply itself twice to give the original expression. To simplify the square root of an expression, we decompose/factor the expression into a product of two terms that are the same. The term of the product is the required square root.
When the radical cannot be conveniently decomposed/factored into two same terms, we factor the radical into a product of a perfect square and a non-perfect square. Using the product/quotient rule of radicals the perfect square is evaluated and the non-perfect square is left as a radical.

I give a big fuckin like to this video
good video
Hello Brian, from across the pond. Excellent video. Iâm beginning to realise that manipulation of these square root problems, was a major gap in my knowledge 55 years ago !! when I did my O and A levels and onto Engineering at UniâŠ..or perhaps itâs my memory đ
I find it very straightforward and yetâŠ..
I do better watching 2 min of this than learning for 45 min in my class. Thank you
well i guess you didn't find the video helpful cause it was 5 minutes
Tom Hopkins idm he was jokingđ
lmaooo same bruhđ
Hahahaha same
Lol....same
9 years later and still a saviour.
10 years later still goin hard
nice pfp
10 years now
12 years later and still popping off
12 years later still slaying
I'm watching this right before my test wish me luck lol
Kryo literally same lmao pre calc

Good luck to everyone here
i srsly was born to not understand math :(
Same

What's so hard to understand. Explain and I'll explain it to you
This video was a bit more confusing than the others. But you basically want to find two numbers that go into 48. That would be 16 and 3
Square root of 16 is 4, and square root of 3 cannot be simplified. So, 4 would go on the outside of the square root, while 3 stays inside
4 Ă sqrt 3
Do you film your lessons as a teacher then post them here? Because thatâs brilliant.. never worry about a sick day again.
yes I do Luca!
@@brianmclogan bro just cut out parts of the video after you record so students arent afraid of asking questions
@@brianmclogan Hey. I'd like to study in your high school is that possible ?
This aged well haha. This is how everything was done for the school shutdowns
Our teacher literally makes us figure everything by ourselves as if we know wtf to do
this user can't be reached Okay...but this is different. He gives us something we donât know how to do and makes us do it. If we say we donât know what to do he tells us to look it up.
I totally understand what ur talking about. Some teachers just aren't meant to be teachers. Some should have retired already because they left their patience in 1765
Just got into 8th grade and i can't understand crap its just so hard for me
take a breath and slow done, this is not a race, you can understand this stuff, practice and give yourself time
Feel you
Same with me but I'm a sevie in accelerated
Im in honors math in 7th grade. So I'm learning this stuff
legit ness same. I took algebra when I was in seventh grade as well.
I think this had been the best video I found yet on simplifying square roots with variables, thank you I am trying to study up for a math placement test for college
wow, this is me right now
@@StudyBlanca Good luck!
nah watch the organic math guy or whatever he has a method which is like 2 steps
I do so much better in class because of your 5 minutes videos than sitting for 1 hr in class. Thank you
My man you have saved me again
I need you as my math teacher
Say no more - Your pfp says it all :P
ikr lol
When youâre watching this 5 minutes before a quiz đ summer school gangđâđŒ
Edit: I got an A on the quiz!!!đđ
congrats! 2 months late but still
Iâm in summer school too
11 years later and this dude is saving me the night before finals
This dude explains it better than alot of teachers ive had thank you
you are a saint. bless your soul. learned more watching this than in class.
Still didn't get it
math has ALWAYS been one of my easiest/favorite courses, but i have a horrible precalc. teacher this year. he rushes through the steps and he never likes to help with the questions we have. heâll just say âgo watch the video on schoology, but itâs just a video of the notes we did and the explanations on how to do the problems are still weak. then on the homework weâll have problems with more steps and nothing in the notes helps me. Iâve never had a B- in math until this year and itâs crazy to know that everything matters on how your teacher presents the material to the class.
Thanks a lot! You are out here SAVING LIVES istg!
Thanks to your videos I got a B on my finalđđŒđ€©
awesome! Congrats to you Nikolas. Happy to be there for you
Donât call this person stupid he tried very hard and a B is not bad thatâs actually an 80 ۧÙ۱ۯۧŰčÙ ÙÙ۱ÙÙ

@@official_lissana2358 ssssss right
I dunno why but I smile and sometimes laugh when I see math teachers taking their time thinking. I could visualize their brain sweating from thinking too hard lol
You are a lifesaver. We're taking a quiz on this on Monday, and this video prepared me a lot.
my final is in 3 hours and you're a quick life saver for all the concepts im still confused on thank you!!!!

đđ Very Good, Brian McLogan, Keep It Up đ đ
Currently Active duty taking online college, pre-calculus was killing me until I came across your videos! THANK YOU!
You must be praised. I have been looking for a good explanation for hours!!!!! That was what I was looking for thanks. Subbed!
Bruh wish I had you as my video teacher, my video teacher is just like *writes down and goes over one problem and expects you to know it*
THANK you omg I canât do math for shit and Iâm in 11th grade....going into consumer math
11 years later its even better
We learn from you from Saudi Arabia teacher. Thank youâ€ïž
Watching this right before my test :/! Thanks for the help :)
Did you do good?
@@izzyyy9471 i got an 100 :)

@@itslululemons6949 i hope u fail all your classes from now on
I have a test on radicals and inverses tomorrow. this helped!!!
This guy is a legend! Thanks so much!
Your videos have saved me- I have a 90 minute algebra class and Iâve learned nothing this year so I have to go home and look stuff up on CZcams.
THANK YOU. idk why i cant understand what my professor is saying, I just couldn't get it but this really helped a lot. THANK YOU!
Ok Iâm in 9th grade and I donât understand how to do -21 radical 27x to the 9th power
Same đ
11 years later and heâs still a legend
12 years later and still a god send
I could go back and rewatch my school's original lesson recording, but it's 40 minutes long and I can't be bothered. This is easier and faster, thank you.
yes.
At 5:04 why is there 2 y's in the index and then when you rewrite it theres only one y on the outside im confused
Gabriela Nevarez BC in algebra, yy would be considered as y^2. Which is y to the 2nd power. So he rewrote the problem so that the y is doubled up? Idrk how to explain it
This video has just helped me so much. It answered so many questions. Thanks, Brian.đ Now I will like and subscribe.
Outstanding!! You should be King of the World.
It all makes sense now youâre a genius
Thank you so much!!
Thank you this video was helpful I was absent and this is what we weâre learning
Mr clean comes in clutch every single time
â(48xÂČyâ”) = 4 |x| yÂČâ(3y) You should consider the case of x
I'm not sure if they have considered domains yet
This would normally be a superfluous step because x is an unknown value. Unless it is equal to something, the unknown value x can remain unknown meaning it can be positive or negative when solving. For argument sake, we'll say that it is positive so it's less for us to do
Right u r
Bro ur such a life saver this one example helped more then a whole tutour
This guy explains in under 6 minutes what my math teacher hasnt been able to make me understand in 3 weeks
the dude at the end "why didin't you do 4 * 12"đ
This dude teaches better than my Math Teacher
i hate to say this bc my algebra 2 teacher is amazing, but this 2 minute clip taught me more than the hr and 15min lecture didđ
this guy a life saver fr
I got a final tmw this is the only thing I donât understand you just saved me đđđ
thank u sir
greetings from Yemen
Thanks a lot man, really appreciate this video. I didn't understand what my algebra teacher was saying, or teaching at all. I finally understand now, so thank you again man.
You are very welcome?!
my final for math is tomorrow i donât get any of the math so i keep looking it up on here and this guy keeps popping up. I get it my teacher doesnât teach so thank you, be my teacher
ive got a math test on radicals tmr... ill update this when i get the grade back :))
dude this guy has helped me so much
I donât even try to pay attention in class anymore because itâs much easier just to watch these kind of vids
But this video is wrong
I want to have you as my teacher because my teacher never explains me the way you do like easy and faster way to learn
You are a genius
Iâm watching this in the middle of my test please help me
Thatâs cheating >:(
wow teacher it was clear for me.
At 4:44 how do you determine what variables go outside and what variables go in the inside?
U must find the square root of each if it has square root then put the square root of it outside
yex
got my sat next month!
Thanks brian mc logan
I wish you were my teacher
I forgot this was a video and I was about to ask a question
a life saver
You should indicate the element of principal root by putting x inside the absolute value symbol.
helped a lot thanks
Glad it helped
Yes, you can simplify the square root of 6 x 8 further; that is square root of 6 x 4 x 2. But if you want to use it is another thing.
You can also simplify the square root of 24 Ă 2 since 4 is multiply of 12 its also a multiply of 24 cause 12 is just half of 24. Also you would get the same numbers (6, 4 and 2)
Please note that the square root of X squared = absolute value of X not just X. This is what many people donât realize.
Can u be my teacher you explain so well đđđ
Army đđ
what do you do if the number under the radical is a perfect square
Kimberly Emile no number will end up on the inside but itâs possible a variable will.
Thank you so much!
You are a great person
Mann you have complicated the problem (its quite easy )
Lmao I know that itâs taken from his last name but can we just talk about how his merch says Logang??? I can only think of Logan Paul
Lol
These vids are god sends,after the online school year,i had no knowledge in my math class due to a mix of it being online,not being able to focus,and being a slacking son of a bitch,only passing thanks to random calculators online,as of current its nipping me in the ass,and yet,these videos are making it possible to survive in my class,and pass no less,despite basically missing a year of math,without these i woulda already been dead in the water man.
more on fraction form. like i know your denomanator cant be in radical is this correct?
why does every other video make us do like 500 other steps when we could literally do this LOL
No idea
why no absolute values around y?
thanks
You need to include the abs value bars in the case that x is a negative number
THANK YOU SO MUCH
To be honest, I think there is a debate to be had as to whether the result is simplified or more complicated!
deff more complicated
Thank you sir,im always watching ur videosđ
Shouldn't there be an absolute value sign around x when it comes out of the radical? Even index, even power inside, odd power outside.
You sr are the GOAT
Thank god for you
boutta buy all ur merch
What about the use of absolute values? Shouldnât the answer be 4abs(xy^4)sqrt(3y)? abs stands for absolute value and start stands for square root. If you try to plug in negative numbers and write without absolute values, it would be undefined under the square root symbol. The absolute values can be negative, which would a positive number.
You got it almost right.
The answer should be:
4abs(xy^2)sqrt(3y) which is equivalent to 4|x|y^2sqrt(3y)
THANK YOU OMG
Isn't the x supposed to be in absolute value notation?
Iâm crying, why is math so hard
Take it step by step
What would I do with a problem like 'simplify the square root of 50xy^2'
You do â50x^2y^2. First you find the square root of 50, which is 5 â2 . 5 â2 times x^2 times y^2 which is 5xy^2 â2
Yes I have many questions
