Irrational

Vedclass · Answer

(B) Assume that $\frac{1}{\sqrt{2}}$ is a rational number.Therefore,we can find two integers $a$ and $b$ $(b 
eq 0)$ such that $\frac{1}{\sqrt{2}} = \frac{a}{b}$.By rearranging the terms,we get $\sqrt{2} = \frac{b}{a}$.Since $a$ and $b$ are integers,$\frac{b}{a}$ is a rational number.This implies that $\sqrt{2}$ is a rational number.However,this contradicts the established fact that $\sqrt{2}$ is an irrational number.Therefore,our initial assumption is false,and $\frac{1}{\sqrt{2}}$ must be an irrational number.
