To determine whether the equation

\[
\frac{3^{-5} \cdot (\sqrt[4]{81})^3}{3^{-4}} = 3^{-6}
\]

is true or false, let's simplify both sides step by step.

1. **Simplify \(\sqrt[4]{81}\)**:
\[
\sqrt[4]{81} = \sqrt[4]{3^4} = 3^{4/4} = 3^1 = 3
\]

2. **Now substitute this back into the equation**:
\[
\frac{3^{-5} \cdot (3)^3}{3^{-4}} = \frac{3^{-5} \cdot 3^3}{3^{-4}}
\]

3. **Using the product property of exponents**:
\[
3^{-5} \cdot 3^3 = 3^{-5 + 3} = 3^{-2}
\]

4. **Thus, we now have**:
\[
\frac{3^{-2}}{3^{-4}}
\]

5. **Using the quotient property of exponents**:
\[
\frac{3^{-2}}{3^{-4}} = 3^{-2 - (-4)} = 3^{-2 + 4} = 3^{2}
\]

6. **So the left side simplifies to \(3^2\)**.

7. **Now compare this to the right side**:
On the right side, we have \(3^{-6}\).

Since \(3^2 \neq 3^{-6}\), the original equation is **false**.

Now let's choose the correct justification based on our analysis:

- **false. there is an error in calculation using the quotient property** is the most appropriate response because the simplification led to \(3^2\) instead of \(3^{-6}\).

Therefore, the correct response is:
**false. there is an error in calculation using the quotient property.**
