$$(-xy)^2(-xy^2)=-x^3y^4$$
Explanation
| $$ \begin{aligned}(-xy)^2(-xy^2)& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}x^2y^2(-xy^2) \xlongequal{ } \\[1 em] & \xlongequal{ }-x^3y^4\end{aligned} $$ | |
| ① | $$ \left( -xy \right)^2 = (-1)^2x^2y^2 = x^2y^2 $$ |
