Answer 1

Answer:

$\huge\tt{SOLUTION→}$

$\frac{1}{ \sqrt{3} + \sqrt{5} } \\ \frac{1}{ \sqrt{3} + \sqrt{5} } \times \frac{ \sqrt{3 - \sqrt{5} } }{ \sqrt{3} - \sqrt{5} } \\ \\ \frac{ \sqrt{3} - \sqrt{5} }{ { \sqrt{3} }^{2} - { \sqrt{5} }^{2} } \\ \\ \frac{ \sqrt{3} - \sqrt{5} }{3 - 5} \\ \\ \frac{ \sqrt{3} - \sqrt{5} }{ - 2} \\ \\ - \frac{ \sqrt{3} - \sqrt{5} }{2}$
