To simplify the expression \( 16^{1/4} \), it helps to express 16 in terms of its prime factors. The most valuable factorization in this context is:
\[ 16 = 4 \cdot 4 \]
This is because:
\[ 16^{1/4} = (4 \cdot 4)^{1/4} = 4^{1/2} = 2 \]
Thus, the correct response that would help simplify the expression \( 16^{1/4} \) is:
16 = 4 ⋅ 4
