Question

simplify by ratializing the denaminator √3-√5÷√3+√5

Answer 1

$\frac{ \sqrt{3} - \sqrt{5} }{ \sqrt{3} + \sqrt{5} } \times \frac{ \sqrt{3} - \sqrt{5} }{ \sqrt{3} - \sqrt{5} }$
$\frac{3 + 5 - 2 \sqrt{15} }{3 - 5} = \frac{8 - 2 \sqrt{15} }{ - 2}$
$\frac{ - 2( \sqrt{15 } - 4)}{ - 2} = \sqrt{15 } - 4$

Answer 2

$\frac{ \sqrt{3} - \sqrt{5} }{ \sqrt{3} + \sqrt{5} } =$
(√3-√5)^2/(3-5)=3+5-2√15/-2=2√15-8/2=
$\frac{ \sqrt{15} - 4}{1}$

and thus the ans.
