Question
Answer
$$(-x^2y)^2(-4xy)^3=-64x^7y^5$$
Explanation
| $$ \begin{aligned}(-x^2y)^2(-4xy)^3& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}x^4y^2-64x^3y^3 \xlongequal{ } \\[1 em] & \xlongequal{ }-64x^7y^5\end{aligned} $$ | |
| ① | $$ \left( -x^2y \right)^2 = (-1)^2 \left( x^2 \right)^2y^2 = x^4y^2 $$$$ \left( -4xy \right)^3 = (-4)^3x^3y^3 = -64x^3y^3 $$ |
