Good teaching sir please live classes lo 9th standard my name pranav
Ya sir my name is saumya
Yes sir my name is anamika
Yes sir please
Nice teaching sir
@@sathimahapatra4309 hi anamika i am harsh how are you
Sir, i have a doubt.
Why can't we write √3/1, √5/1, √6/1, √7/1 etc as rational numbers as all these nos. r written in the form of p/q & also here 'q' is not equal to zero ???
Can anyone help me to understand this problem???
Because is in your Q including (√) when root( π) those are irrational
Example= √4/5
Numerator and denominators must be integer but denominator can not be zero
Thanks sir .I understand your video .it's very perfectly
Hello friends I am prince welcome to magnet brains it's rhymes very interesting 😅
😅😅😂😂
🤣🤣🤣🤣👍👍
Pagal ho kya teacher is God unhe kabhi bura nahi bolna chahie

thank you sir..for this video...this helped me a lot
Shubhra Makar, Thanks for being active on the channel. Do recommend us to your friends.
Sir,i am in class 9 I am following your videos where all concepts are getting cleared thanks for your explanation.
so, my doubt is the value of pie [22/7] is represented in a P/Q form where it is a irrational number not only this other number also in this fashion plz clarify.
Sir give my answer.
Bro just to take a approximation we take π =22/7
For calculation we take pie as 3.14 and 22/7 also gives 3.14 in starting that's why
@@ojsv._.rana_20 bro pie value is 3.14159 and 22/7 value is 3.1428 these both number are different but only the starting number are same.
@@ojsv._.rana_20 pie is an irrational number but 22/7 irrational number..
Than you .... sir ur explanation is really very nice and it’s easy to understand
Ha
Thanks sir its very understandable i like magnet brains🙏🙏🙏🤩🤩🤩😍😍😍😎😎😎😎😎😎

Very nice sir👌👌👍👍
all the natural numbers together with 0 to form the whole number
sir, can we also say that postive whole numbers + negative whole numbers are intergers..?
Whole numbers include 0 and zero is neither positive nor negative
So this statement is technically not correct
You are apsulutly right
