To solve the equation \( \frac{1}{81} = 3^n \), we first rewrite \( \frac{1}{81} \) as a power of 3.

Since \( 81 = 3^4 \), we can express \( \frac{1}{81} \) as:

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

Now, we can set the two sides equal to each other:

\[
3^{-4} = 3^n
\]

Since the bases are the same, we can equate the exponents:

\[
n = -4
\]

Thus, the missing exponent \( n \) is \(-4\).
