Hola!

$\frac{2 \sqrt{2} }{5 - 2 \sqrt{6} }$

$sol. \\ \frac{2 \sqrt{2} }{5 - 2 \sqrt{6} } \times \frac{(5 + 2 \sqrt{6})}{(5 + 2 \sqrt{6})}$

$\\ \frac{10 \sqrt{2} + 8 \sqrt{3} }{ {5}^{2} - {(2 \sqrt{6} )}^{2} } \\ \\ \frac{10 \sqrt{2} + 8\sqrt{3} }{25 - 24}$

$RPTA: \\ \\ 10 \sqrt{2} + 8 \sqrt{3}$
