To simplify the expression \( 2^3 \times 2^{-5} \), we can use the property of exponents that states \( a^m \times a^n = a^{m+n} \).
So, we have:
\[
2^3 \times 2^{-5} = 2^{3 + (-5)} = 2^{-2}
\]
Thus, the expression \( 2^3 \times 2^{-5} \) is equivalent to \( 2^{-2} \).
The correct answer is:
**2^{-2}**
