To find the equivalent value of \( 3^{-4} \), we can use the property of exponents that states \( a^{-n} = \frac{1}{a^n} \).

So,
\[
3^{-4} = \frac{1}{3^{4}}.
\]

Now, we can calculate \( 3^{4} \):
\[
3^{4} = 3 \times 3 \times 3 \times 3 = 9 \times 9 = 81.
\]

Therefore,
\[
3^{-4} = \frac{1}{3^{4}} = \frac{1}{81}.
\]

Looking at the provided options, the equivalent to \( 3^{-4} \) is:
\[
\text{1 over 81}.
\]
