To use the Power Rule of Exponents, we need to identify expressions that involve raising a power to another power. The Power Rule states that \((a^m)^n = a^{m \cdot n}\).
Among the provided options, the expression that correctly utilizes this rule is:
\[ (7^4)^8 \]
This expression can be simplified using the Power Rule to:
\[ 7^{4 \cdot 8} = 7^{32} \]
The other expressions do not properly illustrate the Power Rule of Exponents.
