simplify each expression. Write without negative exponents.

Let's solve the expression shown in the image. The expression given is:

\[
\left(\frac{3x^{\frac{3}{2}} y^3}{x^2 y^{-\frac{1}{2}}}\right)^{-2}
\]

### Step 1: Simplify the expression inside the parentheses

We start by simplifying the fraction inside the parentheses:

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

This can be split into separate parts for \(x\) and \(y\):

\[
3 \cdot \frac{x^{\frac{3}{2}}}{x^2} \cdot \frac{y^3}{y^{-\frac{1}{2}}}
\]

For \(x\):

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

For \(y\):

\[
\frac{y^3}{y^{-\frac{1}{2}}} = y^{3 - \left(-\frac{1}{2}\right)} = y^{3 + \frac{1}{2}} = y^{\frac{7}{2}}
\]

So, the simplified expression inside the parentheses becomes:

\[
\frac{3x^{-\frac{1}{2}} y^{\frac{7}{2}}}{1} = 3x^{-\frac{1}{2}} y^{\frac{7}{2}}
\]

### Step 2: Apply the outer exponent \(-2\)

Now, apply the exponent \(-2\) to the entire expression:

\[
\left(3x^{-\frac{1}{2}} y^{\frac{7}{2}}\right)^{-2}
\]

Distribute the exponent \(-2\) to each term:

\[
3^{-2} \cdot \left(x^{-\frac{1}{2}}\right)^{-2} \cdot \left(y^{\frac{7}{2}}\right)^{-2}
\]

This simplifies to:

\[
\frac{1}{9} \cdot x^{1} \cdot y^{-7}
\]

Or more simply:

\[
\frac{x}{9y^7}
\]

### Final Answer:

The simplified expression without negative exponents is:

\[
\boxed{\frac{x}{9y^7}}
\]
