To simplify the expression \( \frac{8^{-5}}{8^{-3}} \), we can use the property of exponents that states \( \frac{a^m}{a^n} = a^{m-n} \).
Now, applying this property:
\[
\frac{8^{-5}}{8^{-3}} = 8^{-5 - (-3)} = 8^{-5 + 3} = 8^{-2}
\]
Next, we can express \( 8^{-2} \) as:
\[
8^{-2} = \frac{1}{8^2}
\]
Thus, the simplified result is:
\[
\frac{1}{8^2}
\]
So, the correct option from the provided choices is:
- **one divided by the quantity eight squared**
