Question

(-X Y^3Z) (-X^3 y^4 z^3)^3

Answer 1

Given the expression :

`(-xy^3z)\cdot(-x^3y^4z^3)^3`

We will use the following rules :

`\begin{gathered} a^m\cdot a^n=a^(m+n) \\ \\ (a^(m)n)=a^(m\cdot n) \end{gathered}`

so, the answer will be as following :

`\begin{gathered} (-xy^3z)\cdot(-x^3y^4z^3)^3 \\ \\ =(-xy^3z)\cdot(-x^9y^(12)z^9) \\ \\ =x^(10)y^(15)z^(10)^{} \end{gathered}`
