Làm tính chia: (-x^3 y^2 z)^4 : (-xy^2 z)^3

* Hướng dẫn giải

$$\begin{gathered} {\left(-x^3 y^2 z\right)}^4:{\left(-x{y}^2 z\right)}^3 \\ =\left[{\left(-1\right)}^4.x^{3.4} y^{2.4} z^4\right]:\left(-x^{1.3} y^{2.3} z^{1.3}\right) \\ =x^{12} y^8 z^4 : \left(-x^3 y^6 z^3\right)=-x^9 y^2 z \end{gathered}$$
