Answer

$6+2\sqrt3$

Work Step by Step

The distributive property states that for any real numbers $a, b, $ and $c$, $a(b+c) =a\cdot b+a \cdot c$ Thus, apply the distributive property to the given problem to find: $=\sqrt{6 \cdot 2} + \sqrt6 \cdot \sqrt{6} \\=\sqrt{12}+6 \\=\sqrt{4(3)} + 6 \\=2\sqrt{3}+6$
