Answer 2

$<b><u><i>$ Rationalizing the denominator :

$= > \frac{1}{2 \sqrt{2} } \\ \\ = > \frac{1}{2 \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } \\ \\ = > \frac{ \sqrt{2} }{2 \times \sqrt{2 \times 2} } \\ \\ = > \frac{ \sqrt{2} }{2 \times 2} \\ \\ = > \frac{ \sqrt{2} }{4}$

=> Multiply the given numerator and denominator with a number which makes the denominator rational.

=> Here, it is √2.
