To simplify the expression \(4^4 \times (4^{-2})^4\), we can use the properties of exponents.
1. First, we apply the power of a power rule, which states that \((a^m)^n = a^{m \cdot n}\):
\[
(4^{-2})^4 = 4^{-2 \cdot 4} = 4^{-8}
\]
2. Now, we can rewrite the original expression:
\[
4^4 \times 4^{-8}
\]
3. Next, we apply the product of powers rule, which states that \(a^m \times a^n = a^{m+n}\):
\[
4^4 \times 4^{-8} = 4^{4 + (-8)} = 4^{-4}
\]
Therefore, the expression \(4^4 \times (4^{-2})^4\) simplifies to:
\[
4^{-4}
\]
This is the equivalent expression.
