To simplify the expression \((62)^4\) using the Power Rule of Exponents, you can apply the rule that states \((a^m)^n = a^{m \cdot n}\).
In this case, we can rewrite \(62\) as \(6^2\):
\[ (6^2)^4 \]
Now, applying the Power Rule:
\[ (6^2)^4 = 6^{2 \cdot 4} = 6^8 \]
Thus, the simplified expression is:
\[ 6^8 \]
