To simplify the expression \((2^{-1})^4\), we apply the power of a power rule, which states that \((a^m)^n = a^{m \cdot n}\).

  1. Using this rule:

    \[ (2^{-1})^4 = 2^{-1 \cdot 4} = 2^{-4} \]

  2. Next, we know that \(2^{-4}\) can be expressed with a positive exponent by using the rule \(a^{-m} = \frac{1}{a^m}\):

    \[ 2^{-4} = \frac{1}{2^4} \]

  3. Now, we calculate \(2^4\):

    \[ 2^4 = 16 \]

  4. Therefore,

    \[ 2^{-4} = \frac{1}{16} \]

So, the fully simplified expression without any zero or negative exponents is:

\[ \frac{1}{16} \]

Thus, the answer is:

\(\frac{1}{16}\)
