To simplify \( 4^{10} \) using the Power Rule of Exponents, we can express it as \( (4^5)^2 \) since \( 4^{10} \) can be rewritten as \( 4^{5 \times 2} \).
Therefore, the equivalent expanded expression is:
\( (4^5)^2 \)
So the correct response is:
\( (4^5)^2 \) (left parenthesis 4 superscript 5 baseline right parenthesis squared).
