Question

Prove that 1/root2 is an irrational number......

Answer 1

Answer:

1/√2 = a/b

Step-by-step explanation:

We have to prove 1/√2 is irrational

Let us assume the opposite,

I. e. (that is) , 1/√2 is rational

Hence, 1/√2 can be written in form of a/b

where a and b (b≠0) are co prime ( no common factor other than 1)

Hence, 1/√2 = a/b
