Answer 2

$\huge\mathfrak\red {answer}$

$\frac{2}{\sqrt{5}-\sqrt{2}}$

$\frac{5}{ \sqrt{5} - \sqrt{2}} \times \frac{ \sqrt{5} + \sqrt{2} }{ \sqrt{5} + \sqrt{2} }$

$\frac{5 \sqrt{5} + 5 \sqrt{2}}{ {( \sqrt{5}) }^{2} - {( \sqrt{2}) }^{2} }$

$\frac{5 \sqrt{5} + 5 \sqrt{2}}{5 - 2}$

$\frac{5 \sqrt{5} + 5 \sqrt{2}}{3}$
