Simplify. Remember that we have assumed that radicands do not represent the square of a negative number.
-$\sqrt{\left(9 x^{2}\right)^{2}}$
A) $3 x^{2}$
B) $9 \mathrm{x}$
C) $3 \mathrm{x}$
D) $9 x^{2}$

Question

Quizplus · Accepted Answer

The expression simplifies to $9x^2$ because when you square $9x^2$, and then take the square root of the result, you end up with the original expression, $9x^2$, due to the property $\sqrt{x^2} = x$ for non-negative $x$.
