Simplify the radical expression. Assume all variables represent positive real numbers.
-$\sqrt { 567 x ^ { 2 } }$
A) $567 x$
B) $9 \sqrt { 7 x }$
C) $9 x \sqrt { 7 }$
D) $7 x ^ { 2 } \sqrt { 9 }$

Question

Quizplus · Accepted Answer

567 can be factored into 9 * 63, and further into 9 * 9 * 7. Since $x^2$ is under the radical, it can be taken out as $x$, making the simplified form $9x\sqrt{7}$.
