Answer 2

$\sqrt{27} + \sqrt{3} - 4 \sqrt{3} \\ \sqrt{3 {}^{3} } + \sqrt{ 3 } - 4 \sqrt{3} \\ \sqrt{3 {}^{3 + 1} } + \sqrt{3} - 4 \sqrt{3} \\ \sqrt{3 {}^{2} \: . \: 3 {}^{1} } + \sqrt{3} - 4 \sqrt{3} \\ \sqrt{3 {}^{2} \: . \: 3 } + \sqrt{3} - 4 \sqrt{3} \\ \sqrt{3 {}^{2} } \sqrt{3} + \sqrt{3} - 4 \sqrt{3} \\ 3 \sqrt{3} + \sqrt{3} - 4 \sqrt{3} \\ 3 \sqrt{3} + 1 \sqrt{3} - 4 \sqrt{3} \\ (3 + 1 - 4) \sqrt{3} \\ (4 - 4) \sqrt{3} \\ 0 \sqrt{3} \\ \boxed{\boxed{\boxed{0}}}$
