Hey buddy!



Here is yr answer......

$= > \frac{7 + \sqrt{5} }{7 - \sqrt{5} } \\ \\ = > \frac{7 + \sqrt{5} }{7 - \sqrt{5} } \times \frac{7 + \sqrt{5} }{7 + \sqrt{5} } \\ \\ = > \frac{(7 + \sqrt{5}) ^{2} }{(7 - \sqrt{5})(7 + \sqrt{5} ) } \\ \\ = > \frac{49 + 14 \sqrt{5} + 5 }{49 - 5} \\ \\ = > \frac{54 + 14 \sqrt{5} }{44}$
