Question

prove that 1/2 is irrational number

Answer 1

brother your question is wrong you have to say that one by root 2 is irrational because 1 by 2 is rational number I am now proving one by root 2 is irrational number


Let us assume 1/root2 as rational

Let us multiply root2 up and down.

So, root2/2 = a/b ( a and b are integers and b not equal to 0)

root2 = a*2/b

=integer * 2 / integer

= rational

But this contradicts with the fact that root 2 is irrational

Therefore our assumption is wrong, 1/root2 is irrational
