[(x exponent minus 3 times y exponent minus 4 divided by x times y squared)exponent minus 2]exponent three

We are given the expression:

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

Let’s break it down step by step:

### Step 1: Simplify the fraction inside the parentheses
\[
\frac{x^{-3} y^{-4}}{x y^2}
\]
To simplify this, we apply the quotient rule for exponents: \(\frac{a^m}{a^n} = a^{m-n}\). This gives:

\[
\frac{x^{-3}}{x} = x^{-3-1} = x^{-4}
\]
\[
\frac{y^{-4}}{y^2} = y^{-4-2} = y^{-6}
\]

Now, the expression becomes:
\[
x^{-4} y^{-6}
\]

### Step 2: Apply the exponent of -2
We now raise \(x^{-4} y^{-6}\) to the power of \(-2\):
\[
(x^{-4} y^{-6})^{-2} = x^{-4 \times -2} y^{-6 \times -2} = x^8 y^{12}
\]

### Step 3: Apply the exponent of 3
Now, raise the result to the power of 3:
\[
(x^8 y^{12})^3 = x^{8 \times 3} y^{12 \times 3} = x^{24} y^{36}
\]

### Final Answer:
\[
x^{24} y^{36}
\]

This is the simplified expression.
