(2倍铅族根号3-3倍根号2-根号6)(2倍根号3+3倍根号2-根号6)
=(2倍根号3-根号6-3倍根号2)(2倍根号3-根号6+3倍根号2)
=(2倍根号3-根号6)^2-(3倍根号2)^2
=12-12倍根号2+6-18
=-12倍根号2
根号27+[2+根号3]分之1-[根号3-1分之根号3]o次幂
=根号27+[2+友漏根号3]分之1-1
=3倍根号3+2-根号3-1
=2倍根号3+1
根号好激烂12+[2-根号3]分之1-[2+根号3]乘根号3
=2倍根号3+2+根号3-(2倍根号3+3)
=根号3-1
=(2倍根号3-根号6-3倍根号2)(2倍根号3-根号6+3倍根号2)

=-12倍根号2
根号27+[2+根号3]分之1-[根号3-1分之根号3]o次幂
