Question

Proove that 1 by root 2 is irrational

Answer 1

Answer:

Step-by-step explanation:

Let us assume that 1 by root 2 is rational

So, 1 by root2 = a by b where a and b are co-prime

Root 2 = b by a ( reciprocal of 1 by root 2)

LHS is irrational

RHS IS RATIONAL

therefor this is a contradition

Because a and b are co-prime

So 1 by root 2 is irrational
