计算 (1)√75-√54+√96-√108;(2)(1/2)(√2+√3)-(3/4)(√2+√27).计算 (1)√75-√54+√96-√108;(2)(1/2)(√2+√3)-(3/4)(√2+√27).
(1)√75-√54+√96-√108;
=5√3-3√6+4√6-6√3
=√6-√3
(2)(1/2)(√2+√3)-(3/4)(√2+√27).
=(1/2)√2+(1/2)√3-(3/4)√2-(3/4)3√3
=(-1/4)√2-(7/4)√3

(1)√75-√54+√96-√108;
=5√3-3√6+4√6-6√3
=√6-√3
(2)(1/2)(√2+√3)-(3/4)(√2+√27).
=1/2√2+1/2√3-(3/4)(√2+3√3).
=1/2√2+1/2√3-3/4√2-9/4√3
=-1/4√2-7/4√3

1、5√3-3√6+4√6-6√3=√6-√3
2、-1/4√2-7/4√3

(1)√75-√54+√96-√108=5√3-3√6+4√6-6√3=√6-√3;
(2)(1/2)(√2+√3)-(3/4)(√2+√27).=(1/4)(2√2+2√3-3√2-9√3)=(-√2-7√3)/4
