Question

find the value of one upon root 5 +root 2​

Answer 1

$\frac{1}{ \sqrt{5 + \sqrt{2} } } \: rationalise \\ = \frac{1}{ \sqrt{5} + \sqrt{2} } \times \frac{ \sqrt{5} - \sqrt{2} }{ \sqrt{5} - \sqrt{2} } \\ = \frac{ \sqrt{5} - \sqrt{2} }{( \sqrt{5} ) - ( \sqrt{2} )} \\ = \frac{ \sqrt{5} - \sqrt{2} }{5 - 2} \\ = \frac{ \sqrt{5} - \sqrt{2} }{3}$
