Answer 2

Hey !!

Here is your answer....

$= \frac{1}{ \sqrt{5 } + \sqrt{2} } + \frac{1}{ \sqrt{5} - \sqrt{2} } \\ \\ = \frac{ \sqrt{5 } - \sqrt{2} }{5 - 2} + \frac{ \sqrt{5} + \sqrt{2} }{5 - 2} \\ \\ = \frac{ \sqrt{5} - \sqrt{2} + \sqrt{5} + \sqrt{2} }{3} \\ \\ = \frac{2 \sqrt{5} }{3}$
HOPE IT HELPS YOU....

THANKS ^-^
