Answer 1

Hola Mate!!

Your answer :-

$= > \frac{ \sqrt{7} }{ \sqrt{11} + \sqrt{5} } \\ \\ = > \frac{ \sqrt{7} }{ \sqrt{11} + \sqrt{5} } \times \frac{ \sqrt{11} - \sqrt{5} }{ \sqrt{11} - \sqrt{5} } \\ \\ = > \frac{ \sqrt{7}( \sqrt{11} - \sqrt{5} )}{ {( \sqrt{11} )}^{2} - ({ \sqrt{5} )}^{2} } \\ \\ = > \frac{ \sqrt{77} - \sqrt{35} }{11 - 5} \\ \\ = > \frac{ \sqrt{77} - \sqrt{35} }{6}$
