Answer 1

Step-by-step explanation:

$\frac{ \sqrt{5 + 1} }{ \sqrt{5 - 1} } - \frac{ \sqrt{5 - 1} }{ \sqrt{5 + 1 } } \\ \frac{ \sqrt{6} }{ \sqrt{4} } - \frac{ \sqrt{4} }{ \sqrt{6} } \\ \frac{ \sqrt{6} }{2} - \frac{2}{ \sqrt{6} } \\ taking \: lcm \\ \frac{ \sqrt{(6 \times 6)} - 2 \times 2 }{2 \sqrt{6} } \\ \frac{6 - 4}{2 \sqrt{6} } \\ \frac{2}{2 \sqrt{6} } \\ \\ \frac{1}{ \sqrt{6} } ans$
