(3+跟号2-根号2)(3-根号5+根号2)(3根号18+1/5根号50-4根号1/2)除以根号32(3+跟号2-根号2)(3-根号5+根号2)(3根号18+1/5根号50-4根号1/2)除以根号32

(3+跟号2-根号2)(3-根号5+根号2)(3根号18+1/5根号50-4根号1/2)除以 根号32
(3+跟号2-根号2)(3-根号5+根号2)
(3根号18+1/5根号50-4根号1/2)除以 根号32

(3+跟号2-根号2)(3-根号5+根号2)(3根号18+1/5根号50-4根号1/2)除以 根号32
1、(3+跟号2-根号2)(3-根号5+根号2)
=3*(3-根号5+根号2)
=9-3根号5+3根号2
≈6.53
2、(3根号18+1/5根号50-4根号1/2)除以 根号32
=(9根号2+根号2-2根号2)除以4根号2
=8跟号2除以4根号2
=2

1 9-3根号5-3根号2
2 2
