Answer 1

Step-by-step explanation:

factorize by root9+root8

Answer 2

$\huge\mathfrak\green{☟ \: \: \: \: answer \: \: \: \: ✎}$

$\frac{1}{ \sqrt{9 - \sqrt{8} } }$

$= \frac{1}{3 - 2 \sqrt{2} } \times \frac{3 + 2 \sqrt{2} }{3 + 2 \sqrt{2} }$

$Rationalization$

$= \frac{3 + 2 \sqrt{2} }{9 - 8}$

$= 3 + 2 \sqrt{2}$

Hence

$\frac{1}{ \sqrt{9 - \sqrt{8} } } \: is \: equal \: to \: 3 + 2 \sqrt{2}$
