Vedclass · Answer

(A) To rationalise the denominator of $\frac{1}{\sqrt{2}}$,we multiply both the numerator and the denominator by $\sqrt{2}$.$\frac{1}{\sqrt{2}} = \frac{1 	imes \sqrt{2}}{\sqrt{2} 	imes \sqrt{2}}$Since $\sqrt{2} 	imes \sqrt{2} = 2$,we get:$\frac{1}{\sqrt{2}} = \frac{\sqrt{2}}{2}$Thus,the rationalised form is $\frac{\sqrt{2}}{2}$.
