Question

maths question solve it​

Answer 1

Step-by-step explanation:

$\frac{ \sqrt{5} + \sqrt{3} }{ \sqrt{5} - \sqrt{3} } - \frac{ \sqrt{5} - \sqrt{3} }{ \sqrt{5} + \sqrt{3} } \\ = \frac{ {( \sqrt{5} + \sqrt{3} )}^{2} - {( \sqrt{5} - \sqrt{3} )}^{2} }{ { \sqrt{5} }^{2} - { \sqrt{3} }^{2} }$

$= \frac{5 +3 + 2 \sqrt{15} - 5 - 3 + 2 \sqrt{15} }{5 - 3} = \frac{4 \sqrt{15} }{2}$

$= 2 \sqrt{15}$
