${[(-2a^3)*(-2a^2)]^2+(2a^3a^2)^2}/(-1/2a^5)^2$

{[(-2a^3)*(-2a^2)]^2+(2a^3a^2)^2}/(-1/2a^5)^2
=[(4a^5)^2+(2a^5)^2]/(1/4a^10)
=(16a^10+4a^10)/(1/4a^10)
=(20a^10)/(1/4a^10)
=20/(1/4)
=80
再问：再问一个谢谢 (-1/2m^2 n^3-1/4m^3 n^2+1/6mn) / (-1/12mn)-3m(2n^2+mn)
再答： (-1/2m^2 n^3-1/4m^3 n^2+1/6mn) / (-1/12mn)-3m(2n^2+mn) =6mn^2+3m^2n-2-6mn^2-3m^2n =-2
