2√2 + 6√2  -4√2
8√2 - 4√2
4√2

Answer 2

$\[\huge 2\sqrt{2} + 3\sqrt{8}-\sqrt{32}\\2\sqrt{2} + 3\sqrt{2^3}-\sqrt{2^5}\\2\sqrt{2}+3\sqrt{2^2.2}-\sqrt{2^4.2}\\2\sqrt{2}+3.2\sqrt{2}-2\sqrt{2^2.2}\\2\sqrt{2}+6\sqrt{2}-2.2\sqrt{2}\\2\sqrt2+6\sqrt{2}-4\sqrt2\\\left [8\sqrt{2}-4\sqrt{2}=4\sqrt{2} \right ]\]$
