SOLUTION

=> Prove that 1/2 is irrational.

we have to prove that \sf\dfrac{1}{\sqrt{2}} is irrational.

Let us assume that \sf\dfrac{1}{\sqrt{2}} is rational

So,

\sf\dfrac{1}{\sqrt{2}} can be written in the form \sf\dfrac{p}{q}

where p and q (q ≠ 0) are co prime.

Hence,

\sf\dfrac{1}{\sqrt{2}} = \sf\dfrac{p}{q}

Let us write the reciprocal of this..

\sf\dfrac{q}{p} = \sf\sqrt{2}

But we already know that √2 is irrational..

and \sf\dfrac{q}{p} is rational...

Since, rational ≠ irrational

.•. our assumption is incorrect

Hence, \sf\dfrac{1}{\sqrt{2}} is irrational.
