根号32-3倍根号2分之1+根号2
=根号（16*2）-3根号(2/4)+根号2
=根号16*根号2-3根号2/根号4+根号晌没迅2
=4根号2-3根号察历2/2+根号2
=(4-3/2+1)根号2
=7根号宴此2/2

根号32-3倍根号2分老拆之1+根号2
=根号侍芦枣（16*2）-3根号(2/4)+根号2
=根号16*根号2-3根号2/根号哗如4+根号2
=4根号2-3根号2/2+根号2
=(4-3/2+1)根号2
=7根号2/2 =√(16*2)-3(√2)/2+√2
=4(√2)-3(√2)/2+√2
=(√2)(4-3/2+1)
=7(√2)/2

原式＝4根号2－2分之3根号2加根号2=2分之7根号2。关键是化为统一的形式即根号2。

=√(16*2)-3(√2)/2+√2
=4(√2)-3(√2)/信闹2+√2
=(√滑顷罩2)(4-3/2+1)
=7(√乎尘2)/2
