[5/6+7/12/(-3/2)-(-2/3)的2次方】/(-5/36)
问题描述:
[5/6+7/12/(-3/2)-(-2/3)的2次方】/(-5/36)
答
[5/6+7/12/(-3/2)-(-2/3)的2次方】/(-5/36)
=[5/6+(7/12)×(-2/3)-4/9] ×(-36/5)
=(5/6)×(-36/5) + (-7/18)×(-36/5) -(4/9)×(-36/5)
=-6 + 14/5 + 16/5
=-6 + 30/5
=-6+6
=0
或者:
[5/6+7/12/(-3/2)-(-2/3)的2次方】/(-5/36)
=[5/6+(7/12)×(-2/3)-4/9] /(-5/36)
=[5/6- (7/18) -4/9] /(-5/36)
=(15/18 - 7/18 - 8/15)/(-5/36)
=0/(-5/36)
=0
