Answer 1

HEY MATE HERE IS YOUR ANSWER

$\rule {160}{2}$

$= > \frac{10}{ \sqrt{7} - \sqrt{5} }$

$= > \frac{10}{ \sqrt{7} - \sqrt{5} } \times \frac{ \sqrt{7} + \sqrt{5} }{ \sqrt{7} + \sqrt{5} } = \frac{10 \sqrt{7} +10 \sqrt{5} }{7 - 5}$

$\huge = > \frac{ 10\sqrt{7} - 10\sqrt{5} }{2}$
$\rule {135} {2}$
