(1)2√3-3√5-√5+5√5+7√3
=(2√3+7√3)+(5√5-√5-3√5)
=9√3+√5
(2))√12-√27-√20+√50
=2√3-3√3-2√5+5√2
=5√2-2√5-√3
(3))√4x+2√2x-1/2√8x-4√x(x≥0)
=2√X+2√2X-√2√X-4√X
=√2X-2√X
这是我在静心思考后得出的结论,
如果不能请追问,我会尽全力帮您解决的~
如果您有所不满愿意,请谅解~

(1)2√3-3√5-√5+5√5+7√3
=9√3+√5

(2)√12-√27-√20+√50
=2√3-3√3-2√5+5√2
=-√3-2√5+5√2

(3)√4x+2√2x-1/2√8x-4√x(x≥0)
=2√x+2√2x-√2x-4√x
=-2√x+√2x
