The value of $\sqrt{16 \times \sqrt{16}}$ is
(A) $2^{1}$
(B) $2^{2}$
(C) $2^{3}$
(D) $2^{4}$
(E) $2^{5}$

Part B: Each correct answer is worth 6.
Evaluating,

$$
\sqrt{16 \times \sqrt{16}}=\sqrt{16 \times 4}=\sqrt{64}=8
$$

Since $8=2 \times 2 \times 2=2^{3}$, then $\sqrt{16 \times \sqrt{16}}=2^{3}$.

ANSWER: (C)
