Answer 2

Step-by-step explanation:

in numerator denominator case, if denominator is in a+b form then it is multiplied witha-b .

so

$\frac{1}{ \sqrt{2} + \sqrt{8} } \times \frac{ \sqrt{2} - \sqrt{8} }{ \sqrt{2} - \sqrt{8} }$

$\frac{ \sqrt{2} - \sqrt{8} }{( \sqrt{2}) {}^{2} - ( \sqrt{8}) {}^{2} }$

$\frac{ \sqrt{2} - \sqrt{8} }{ - 6}$

$- 6( \sqrt{2} - \sqrt{8})$

$6 \sqrt{8} - 6 \sqrt{2}$

here is your answer
