Answer
Choice B
Work Step by Step
Using the properties of radicals, the expression, $
\sqrt{48}
$, is equivalent to
\begin{align*}
&
\sqrt{16\cdot3}
\\&=
\sqrt{16}\cdot\sqrt{3}
&(\text{use }\sqrt{ab}=\sqrt{a}\cdot\sqrt{b})
\\&=
4\sqrt{3}
.\end{align*}
With $\sqrt{48}$ equivalent to $4\sqrt{3}$, then $\sqrt{48}$ can be simplified. Hence, Choice B.
