The mathematical expression in the image can be interpreted as follows:

\[
\left[ \frac{\left( 3x^{-2}y^3 \right)^4 \left( x^5 y^{-6} \right)^{-6}}{9x^{-4}y^2} \right]^{-2}
\]

### Step-by-step breakdown:

1. **Inside the numerator:**

   - The first term is \(\left( 3x^{-2}y^3 \right)^4\), which we expand by raising both the coefficients and variables to the 4th power:
     \[
     \left( 3x^{-2}y^3 \right)^4 = 3^4 \cdot x^{-8} \cdot y^{12} = 81x^{-8}y^{12}
     \]

   - The second term is \(\left( x^5 y^{-6} \right)^{-6}\), which involves raising each variable to the power of \(-6\):
     \[
     \left( x^5 y^{-6} \right)^{-6} = x^{5(-6)} \cdot y^{-6(-6)} = x^{-30} \cdot y^{36}
     \]

   So, multiplying these together:
   \[
   81x^{-8}y^{12} \cdot x^{-30}y^{36} = 81x^{-38}y^{48}
   \]

2. **In the denominator:**
   The expression is \(9x^{-4}y^2\).

3. **Now, simplify the fraction:**

   \[
   \frac{81x^{-38}y^{48}}{9x^{-4}y^2} = \frac{81}{9} \cdot x^{-38 + 4} \cdot y^{48 - 2} = 9x^{-34}y^{46}
   \]

4. **Apply the outer exponent \(-2\):**

   \[
   \left( 9x^{-34}y^{46} \right)^{-2} = 9^{-2} \cdot x^{-34(-2)} \cdot y^{46(-2)} = \frac{1}{81} \cdot x^{68} \cdot y^{-92}
   \]

Thus, the simplified expression is:

\[
\boxed{\frac{x^{68}}{81y^{92}}}
\]
