Answer 2

Hey dear ‼️

Proof...

Let us take on contrary that 3 root 7 is rational. then there exist two co prime numbers a and b such that ___

3root 7 = a/b

=> root 7 = a / 7b

Now LHS is an irrational no. whereas RHs is rational

this contradiction has arised due to our wrong assumption in beginning .

Therefore 3 root 7 is an irrational number...
