Question

rationalise the denominator of the following​

Answer 1

$= \frac{1}{ \sqrt{3} + \sqrt{5} } \times \frac{ \sqrt{3} - \sqrt{5} }{ \sqrt{3} - \sqrt{5} }$

$= \frac{ \sqrt{3} - \sqrt{5} }{ (\sqrt{3 } ) {}^{2} - ( \sqrt{5}) {}^{2} }$

$= \frac{ \sqrt{3} - \sqrt{5} }{3 - 5}$

$= \frac{ \sqrt{3} - \sqrt{5} }{ - 2}$

$= \frac{ \sqrt{5} - \sqrt{3} }{ 2}$
