To simplify \( \left[\left(x^{-2}\right)^{-2}\right]^{-2} \), we can simplify it step by step. First, let's evaluate the innermost expression: \[ \left(x^{-2}\right)^{-2} = x^{(-2) \cdot (-2)} = x^4 \] Now we substitute this back into the original expression: \[ \left[x^4\right]^{-2} = x^{4 \cdot (-2)} = x^{-8} \] So, the simplified expression is: \[ \boxed{x^{-8}} \]
