Simplify the radical expression. If appropriate, include absolute values.
-$\sqrt { ( b + 2 ) ^ { 2 } }$
A) $| b + 2 |$
B) $\sqrt { \mathrm { b } } + 2$
C) $| b - 2 |$
D) $\mathrm { b } + 4$

Question

Quizplus · Accepted Answer

Simplifying the expression inside the square root gives $b+2$. Since the square root only outputs non-negative values, we take the absolute value to get $|b+2|$. Therefore, $\sqrt {(b+2)^2}=|b+2|$.
