To simplify the expression \( \frac{4^3}{4^5} \), we can use the property of exponents that states:
\[
\frac{a^m}{a^n} = a^{m-n}
\]
Applying this property here:
\[
\frac{4^3}{4^5} = 4^{3-5} = 4^{-2}
\]
Now let's write down the equivalent terms from the given responses:
1. \( \frac{1}{4^2} \): This is equivalent because \( 4^{-2} = \frac{1}{4^2} \).
2. \( 4^2 \): Not equivalent because \( 4^{-2} \) is not equal to \( 4^2 \).
3. \( 4^{-2} \): This is exactly equivalent to the simplified expression.
4. \( \frac{1}{16} \): This is equivalent because \( 4^{-2} = \frac{1}{4^2} = \frac{1}{16} \) since \( 4^2 = 16 \).
5. \( -4^2 \): Not equivalent because \( -4^2 \) equals \(-16\), which is not equal to \( 4^{-2} \).
So the equivalent terms to \( \frac{4^3}{4^5} \) are:
- \( \frac{1}{4^2} \)
- \( 4^{-2} \)
- \( \frac{1}{16} \)
Therefore, the responses that are equivalent to \( \frac{4^3}{4^5} \) are \( \frac{1}{4^2} \), \( 4^{-2} \), and \( \frac{1}{16} \).

Therefore, the responses that are equivalent to \( \frac{4^3}{4^5} \) are \( \frac{1}{4^2} \), \( 4^{-2} \), and \( \frac{1}{16} \).
