答案

[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
