Homework given by Sir:
25:34 (1) 0.32 = 32/99
1:12:38 (2) find to irrational number between 0.158 and 0.16 = 0.159632, 0.159743
Nice brother😊
@@itsdaxHT3NTHPOT Thanks
@@ConfidentGamerz You should be in pinned comment ❤
Sir i have no words for you
You are the best maths teacher which i seen .
These students have awesome teacher
Are u not included in it
Yes
Protip: When the denominator is 7 . The divison will start repeating after 6 digits for example if you divide 10/7 , it will start repeating after 6 digits for sure.
it's a very known fact

Thank you sir amazing teaching . Sir app tension mat liziya app bhoot achha pada raha hai .👍👍🤩🏆
Sir you have left a point that in terminating number, in the form of p/q the denominator i .e q has no other factor than 2 and 5.😊

I love your teaching style, sir! I was focused during the whole class and it really surprised me because I usually have a hard time focusing on something.
Skill issue💀💀( its a joke we made in class lmao) no offence

Konsa cut wla scene?

Q=Why 0.9bar is equal to 1
A=Because there is ultimately no room between 1 and these numbers, the point 1 must be this least point, and so 0.999... = 1.
Bro we can do it with round off also
@@saranshthakur3365 yes
You are amazing sirrrr. Plss keep on teaching sir.. your teaching methods are woww. And we all students love you and physics wala foundation... Students need teachers like you even in the school. School teachers don't teach in the manner you teach. I just love your teaching... Thankyou sirr
❤❤
Sir you are really an amazing teacher. I also sometimes forgot the lines in between as you did but you handled That is very good manner. It is very difficult to learn this much long script and all the teachers are doing this for us. Thanks a lot to all the teachers of physics wallah
Are bhai they don't learn it's not a script vo to bas apni slides banakar thoda sa prepare karte hain baki to khud on the spot bolte Hain
Hats off to all the teachers ❤️
they don't learn the script. The words are their own. They're the best teachers in this world.......
Sir 42/100 pls
Earlier this whole chapter was very boring for me but after attending your class, my view towards this chapter is totally changed.
enjoyed a lot, Whole scenario is totally changed from physics wallah foundation group.

Thank u sir to clear all my doubts
25:40 answer is 32/99
Yes
Thanku sir for the easiest explanation 😃
Thanks a lot sir ....now I am interested in maths
I am watching this video before one day of exam . And it's very help full for me , thankyou very much sir .
Same 😅😅😂😂😂
Yaar teacher kaha se le aaye hai bhai itna accha padte hai yaar aise teacher har ek school main ho toh humara desh kaafi develop ho jayega
@Vandana Gupta par aise teacher milte bhi kam hai
@Vandana Gupta yup
Very nice sir ❤️🙏😊
Thanks a lot 😊❤️🙏
1:12:39 Sir done 🤝🏻 both question
I'm watching this video for my sister to teach her ..and i must say u r the best teacher ..i understand whole concept in one go ..thank u soo much sir ❤
Sir aapse pdhkar hmlogo ko bhut jyada hi achha lg rha hai...
Your teaching is best sir ❤️
I like the way he is so punctual about the time he is watching his watch again and again
People who are punctual are very successful
Thank you so much sir you are the best math teacher ✨
sir your explanation is outstanding !!! you are wonderful .... also there is no faaltu promotion of any paid course throughout the video
Very good teaching sir I am understanding all the topics very clearly it is very now to understand maths for me and i think all of you are also understanding
KEEP IT UP SIR😀😀😀😀🙂
Thank u very much sir aapne bhut aacha explain kiya bich me samajh nhi arha tha prr jab solve kiya to bhut easy lag rha🙏🙏
Thanks Sir for your Best explanation and clarity of the concept...May I request you to please explain y irrational no is as you categorize it as non repetitive as you illustrate the example of 22/7
Sir i helped me too much to flex between my cousions and classmates 😁😁 that you teach to represent root 11 on no. Line q🤩🤩🤩
Another method to solve this question.
5x+ 5x+1= 150
5x+5x+1= 5 square + 5 cube.
Both fives on both sides gets cancelled.
Remaining portion,
x+x+1= square + cube
x+x+1=2+3
x+x+1= 5
2x+1= 5
2x= 4
x = 2.
Finished. Thanks.
galat hai
@@ashishraj8106 kaise galat hai ji.
x+x+1= 2x+1 to hogaya lekin 5 = 2 kaise hua??😂
apne kam se kam kre
@@bhavishyagoswami711 sahi hain and thanks for this
This teacher has amazing teaching 👏👏
Thankyou so much sir ❤️
Thanku a lot sir....
And teams of physics wallah 🙂
Sir if we have to represent the square root spiral in negative line then how we have to represent that
Example - root -2,-3,-5 and etc
You should to do that in the right side of the number line ,
Amazing sir your Teaching method is fabolus 😊😊😊
Sir as per your homework let's take a irrational number 4+√3 and other 5+√3 ans will be rational and 4+√2*5+√3 will be irrational
30:05 sir aapki is smile se mujhe bhi hasi aagyi 😂😂
Sir reason ye hai ki 0.9 bar is appx.equal to 1
Sir (√2)² is 1.999999.. which is appx. Equal to 2 and we consider it
Chapu😂😂😂
@@kartunbaba kya matlab 😂
Hoorah we reached 100k 🤩🤩🤩🤩🤩🤩🤩🤩
Thanks you sir after seeing this view I understand this chapter easily and better than other teachers
I can say physics wallah teachers are great. Specially Mathematicians.
Sir told the person to cut the Clip but he uploaded video without Editing 🤣 But I must say Sometimes it Happens because they are also Human not God....
But overall this Video was very Helpfull....Thank you Sir 🙏
❤️❤️❤️ yaa !!!
Sir actually my favourite teacher.❤️❤️❤️❤️❤️Really SALUTE🙏🙏
Very nice Explanation sir i got all my concepts cleared 🖤
Very good explanation and very nice teacher this is very helpful to me for tommorow test
1:00:55 0⁰=1, Because the rule is variable will always be whole number, so it doesn't matter if we write A⁰=1 or 0⁰=1 both should remain same.Right?
no, it is undefined.
@@anirbandey7384 yes
Sir answer of que 0.32 bar is 32/99 and 0.9bar =1 this because it is rational no. That is non terminating but repeating not sure about the second answer
Thank u sir 🙏
Thanks sir its so useful for me u just solved my all doubt ,I'm so weak in maths 😅 💜💜
Mohit poonia sir is OP after watching sir explanation video maths is seems like a easy and it's understand quickly....
THANK YOU A LOT SIR FOR CLEAR US ALL DOUBT....✌👏
😊😍Sir you teaches very amazing and fantastically. Your voice is full of motivation and joy.🥰😋😎

I am also jnv student
Jnv is going to start ❤️❤️
Jara padhai me bhi comment karo sirf taarif me nhi
Sir, I have a doubt that in questions for the laws of exponent in the first question shouldn't we divide the bases means subtract first then multiply means addition
Bhai time stamp bata do
Yes u can do that but this one is the easier way to solve so that's why sir had used this one.
Plz tell i m. Very much confused in non terminating bt repeating in which we have to represent it in p/q form
Mind blowing teaching sir hats off to you thank you so much for coming in our lives ur the best teacher ever 🙏😊😊
He pw team 💥 I want to ask you that 😂😅 starting me hello baccho kon bolta he sari videos me
Me guess= alak pandey sir💥💥💥
Thank you so much Sir.........you are great and wonderful teacher...and ur explanation is amazing.....😀
Yaaa!!!!
0.9 (bar) is equal to 1 because nine is going on repeating so it is being rounded off
This is the first channel which I found easy to understand for myself
Sir, these classes is better than online classes.😁😁😁
Thank you very much sir. You teach very well and we understand maths very interesting and easy way.
0.9^- is 1 because if we divide 1by3 then we got 0.9999999 Which is repeating so, we can write it as 0.9^-
Hence,0.9^-=1
TRUST ME YOUR ARE A BEST TEACHER EVER 🤩🤩 😘
I got full 20/20(means full 100%)in math UT always after 7th class
Sir well explained keep it up
Sir your concepts are so usefull 👌👌
You are the best ever teacher sir love u are my real teacher 💞,🙇🙇🙇🙏🙏🙏
Question no. 3.
32 bar
x=0.323232.....(1)
100x=32.323232....(2)
(2)-(1)
99x=32
x=32/99.
Hence,the required answer is 32/99.
Sir you are a very *awesome* and *splendid teacher* which I never been seen before.😎😎🎉🎉🔥🔥
Best teacher ever I am enjoying
Sir you are great teacher no doubt but sir you cannot explain deeply but thank you sir to give us your precious time
Sir apne ×100 karke 1000 kiya aur phir 10 se subtract kyun kiya I have this doubt in question no.4 in 28:46 sir can you pls solve this doubt
Bcz we should be able to subtracte the repeating numbers
Bhai mixed repeating sawaal tha to pehle pure repearting bnaya tha na to value 10 aayi thi, fir use solve kiya to 1000x aaya, to eq2-eq1= 1000x-10x hua
Sir loved it 🖤
Superb
just loved the method of teaching
