Answer 1

1)

$</p><p>\sf \rightarrow \quad \frac{1}{2 - \sqrt{5} } \times \frac{2 + \sqrt{5} }{2 + \sqrt{5} } \\ \\ \sf \rightarrow \quad \frac{2 + \sqrt{5} }{4 - 5} \\ \\ \sf \rightarrow \quad - (2 + \sqrt{5} )</p><p>$

2)

$</p><p>\sf \rightarrow \quad \frac{1}{ \sqrt{6} } \times \frac{ \sqrt{6} }{ \sqrt{6} } \\ \\ \sf \rightarrow \quad \frac{ \sqrt{6} }{6} </p><p>$
