Answer 1

Answer:

2(√3+√5)/(√3-√5)*(√3+√5)

=(2√3+2√5)/(3-5)

= -(√3+√5) 【Answer】

Step-by-step explanation:

Answer 2

$\frac{2}{ \sqrt{3} - \sqrt{5} } \\ \\ = \frac{2}{ \sqrt[]{3} - \sqrt{5} } \times \frac{ \sqrt{3} + \sqrt{5} }{ \sqrt{3} + \sqrt{5} } \\ \\ = \frac{2 (\sqrt{3} + \sqrt{5} )}{3 - 5 } \\ \\ = \frac{2( \sqrt{3} + \sqrt{5}) }{ - 2} \\ \\ = - \sqrt{3} - \sqrt{5}$
