(-2a^3b^2c)^3除以(3a^2b^3)^2+(-a^4c)8(-2ac^2)

问题描述:

(-2a^3b^2c)^3除以(3a^2b^3)^2+(-a^4c)8(-2ac^2)
中间的除以是除号的意思

8是不是乘号的意思?(-2a^3b^2c)^3÷(3a^2b^3)^2+(-a^4c)*(-2ac^2)=(-8a^9b^6c^3)÷(9a^4b^6)+(-1)*(-2)*(a^4*a)*(c*c^2)=(-8/9)*(a^9/a^4)*(b^6/b^6)*(c^3)+2a^5c^3=(-8/9)a^5c^3+2a^5c^3=(-8/9+2)*a^5c^3=10a^5c^3/...
