Answer 1

HEYA!!

$\frac{ \sqrt{ \sqrt{5} + 2 } + \sqrt{ \sqrt{5} - 2 } }{ \sqrt{ \sqrt{5} + 1} }$

identity uesd :

${a}^{2} - {b}^{2} = ( a + b) ( a-b )$

$\frac{ (\sqrt{ \sqrt{5} })^{2} - (2)^{2} }{ \sqrt{ \sqrt{5} + 1 } }$

$\frac{ \sqrt{5} - 4}{ \sqrt{ \sqrt{5} - 1} }$

on rationalisation,

$= \frac{ \sqrt{5} - 4 \times \sqrt{ \sqrt{5} + 1} }{ \sqrt{ \sqrt{5} - 1 \times \sqrt{ \sqrt{5} + 1} } }$

$\frac{ \sqrt{5} - 4 \times \sqrt{ \sqrt{5} - 4 } }{ \sqrt{5} - 1 }$

you can do the further evaluation now i think
