Question

$\frac{ \sqrt{2 - \sqrt{5} } }{ \sqrt{2 + \sqrt{5} } }$

Answer 1

Hi there

Your answer is :-

$\frac{ \sqrt{2 - \sqrt{5} } }{ \sqrt{2 + \sqrt{5} } }$

$-(2 - \sqrt{5})\times(2 - \sqrt{5})$

$-(2 - \sqrt{5})^2$

$-(4 - 4 \sqrt{5} + 5)$

$-(9 - 4 \sqrt{5})$

$- 9 + 4 \sqrt{5} ( Ans )$

Thank You
