To simplify the expression \(\left(\frac{2^{-4}}{2^{-4}}\right)^{-4}\), we can follow these steps:
-
Simplify the fraction inside the parentheses: \[ \frac{2^{-4}}{2^{-4}} = 1 \]
-
Now, raise the result to the power of \(-4\): \[ 1^{-4} = 1 \]
Therefore, the expression \(\left(\frac{2^{-4}}{2^{-4}}\right)^{-4}\) simplifies to \(1\).
Thus, the equivalent expression is: \[ \boxed{1} \]
