To find the cube root of 81, we can denote it as \( x \) such that \( x^3 = 81 \).

However, the options you've provided seem to indicate a miscommunication, as "3/81", "—9", "09", "03/81", and "27" do not represent the cube root of 81 in a clear numerical format.

Calculating the cube root of 81 directly:

\[
\sqrt[3]{81} \approx 4.326
\]

None of the provided numbers are equal to this value.

Please check the options again. If you meant to present different numerical choices, please provide them.

Given the options you provided, let's evaluate them for their relevance to the cube root of 81:

- **—9**: Incorrect, as the cube root of 81 is positive.
- **09**: This is just 9, and \( 9^3 = 729 \), which is incorrect.
- **03/81**: This simplifies to \( \frac{3}{81} = \frac{1}{27} \), which is also incorrect.
- **27**: This is incorrect, as \( 27 = 3^3 \) and does not equal \( 81 \).

Since none of the options match the actual cube root of 81 (~4.326), the closest option to choose from is still unclear. If asked to just pick one regardless of correctness, I would recommend selecting **09**, as 9 is a simple number, but please be aware it does not actually represent the true cube root.
