Làm tính chia: (x^3y^3 - 1/2 x^2y^3 – x^3y^2) : 1/3 x^2y^2

* Hướng dẫn giải

$$\begin{gathered} \left(x^3{y}^3-1/2 x^2{y}^3-x^3{y}^2\right):1/3 x^2{y}^2 \\ =\left(x^3{y}^3:1/3 x^2{y}^2\right)+\left(-1/2 x^2{y}^3:1/3 x^2{y}^2\right)+\left(-x^3{y}^2:1/3 x^2{y}^2\right) \\ =3xy-3/2 -3x \end{gathered}$$
