Question

Solve this question:-
(√5-√3) (√5 +√3) ​

Answer 1

Answer:

5-3=2 is the right answer

Answer 2

Answer:

$( \sqrt{5} - \sqrt{3} )( \sqrt{5} + \sqrt{3} )$

$it \: is \: in \: the \: form \: of \: (x + y)(x - y)$

$(x + y)(x - y) = {x}^{2} - {y}^{2}$

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

$= 5 - 3$

$= 2$
