Proof: √2 is irrational (Hindi)

Anmol proves that the square root of 2 is an irrational number, i.e. it cannot be given as the ratio of two integers.

Why We Choose Contradiction Method ?

[@dy4728]

Search for history of it and √2

[@neeldutta7]

Sir when a & b are even , this means that they are multiple of 2 So we can write *a* as 2m & *b* as 2a So they can be reduced to lowest term that is *m/a* So how can we say that this is not rational..?????

[@Wixzone792]

Who states that a and b are even well they both are at their *simplest form* that states that they can't divide more so they are prime number and they have no common factor other than 1. Hope you understand😊

Thank you sir

Very very very good sir ji i salute sir

[@molinaghosh6063]

Very nicely explained

[@anilkumar-nu3cd]

Rational no means it is in the form of a/b and ab coprimes coprimes means any set has common factor 1 like 4and 5

[@nikhilniki7295]

What if we asume root 9 is rational and do this process, we end up with 9 as a common factor. And so is it irrational?

[@amishappadagal7497]

No ,root 9 is rational because it is the square of 3 which can be written as 3 by 1 which is rational and irrational numbers are square of non hence, root 9 is rational

[@vishal-sr5et]

If p is a PRIME NUMBER ,and a2 is divisible by 2,then only we can write, a is divisible by p So here when u will solve by this method ,u will come across 9,which is not prime number

[@mtp7424]

That's this proof is wrong

Rational no is in the form of a÷b here a and b coprimes that's the definition coprimes means here any two nos have common factor 1 like the set 4and 5 7and 10

Thanks boi

[@sayedurrahman7167]

Why is it necessary to have p by q as co prime???

[@khanacademyindia]

Hi Sayedur Rahman. Thanks for asking such a nice question. Even if we assume that sqrt(2) is equal to some fraction m/n, which is not in its simplest form but still m/n can always be reduced to a/b anyway. Hence, sqrt(2) is still equal to a/b where a and b are co-prime. Would like to hear more from other learners. Thanks

[@manshii.k22]

Thank-you sir....I understand this very easily..uh made it so interesting and clear✨

[@anilkumar-nu3cd]

Finally we get a b have common factor 2 then we simplify we get co primes so how it contradicts
