Answer 2

Hello Mate!

$\sqrt{2} ( \sqrt{6} - \sqrt{18} ) = \sqrt{12} - \sqrt{36}$

$\sqrt{3} ( \sqrt{27} - \sqrt{6} ) = \sqrt{81} - \sqrt{18}$

$3 \sqrt{2}$

Now,

$\sqrt{12} - \sqrt{36} + \sqrt{81} - \sqrt{18} + 3 \sqrt{2} \\ \sqrt{12} - 6 + 9 - \sqrt{18} + 3 \sqrt{2} \\ 2 \sqrt{3} + 3 - 3 \sqrt{2} + 3 \sqrt{2} \\ 2 \sqrt{3} + 3$

Hope it helps☺!
