Question

Simply (√5-√3)(√5+√3)

Answer 1

Hey mate here is the solution

We are using the formula

(a-b) (a+b) =a^2-b^2

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

The answer is 2

Hope it helps

Answer 2

$\huge\mathcal\red{Answer}$

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