Answer 2

$( \sqrt{18} + \sqrt{8}) * ( \sqrt{18} + \sqrt{8}) \\ \\ \\ (\sqrt{18})^2 + \sqrt{18}* \sqrt{8} + \sqrt{18}* \sqrt{8} + (\sqrt{8})^2 \ \\ \\ \\ (\not \sqrt{18})\not ^2 + \sqrt{2 * 3^2}+ 2\sqrt{2} + \sqrt{2*3^2}+ 2\sqrt{2} + (\not \sqrt{8})\not^2$

$18 +3\sqrt{2}+ 2\sqrt{2} + 3\sqrt{2}+3 \sqrt{2} + 3\sqrt{2}+ 8 \\ \\ 18 + 3 * 2 (\sqrt{2})2 + 3*2 ( \sqrt{2})^2 + 8 \\ \\ 18 + 3 * 2 * 2 + 3*2*2 + 8 \\ \\ 18 + 12 + 12 + 8 \\ \\ => 50$
