=(3√3-1/2-√3)x2√3
=3√3x2√3-1/2x2√3-√3x2√3
=18-√3-6
=12-√3

(√27-1/2-√3)x√12
=(3√3-1/2-√3)x√12
=(2√3-1/2)x√12
=2√3x√12-1/2x√12
=2√36-1/2x2√3
=12-√3

(√27-1/2-√3)x√12
=(3√3-1/2-√3)x√12
=(2√3-1/2)x2√3
=12-√3

答：
[(√27-1) / (2-√3)]*√12
=√12*(3√3-1)(2+√3) / [(2+√3)(2-√3)]
=2√3*(6√3+9-2-√3) /(4-3)
=2√3*(5√3+7)
=10*3+14√3
=30+14√3
