Answer
$\frac{1}{32}$
Work Step by Step
The negative exponent rule states that for every nonzero number $a$ and integer $n$, $a^{-n}=\frac{1}{a^n}$.
Therefore, $2^{-5}=\frac{1}{2^{5}}$
Finally, we simplify the exponent on the denominator by expansion giving us: $\frac{1}{2\times2\times2\times2\times2}=\frac{1}{4\times4\times2}=\frac{1}{32}$
