Use the power rule and the power of a product or quotient rule to simplify the expression.
-$( - 4 \mathrm { pqr } ) ^ { 2 }$
A)-8pqr
B)16pqr
C)- $- 8 p ^ { 2 } q ^ { 2 } r ^ { 2 }$
D) $16 p ^ { 2 } q ^ { 2 } r ^ { 2 }$

Question

Quizplus · Accepted Answer

When you square $(-4pqr)^2$, you square both the coefficient and each of the variables inside the parenthesis. Thus, $(-4)^2 = 16$ and $p^2, q^2, r^2$ are the squared variables, making the simplified expression $16p^2q^2r^2$.
