From the image you provided, it looks like you're simplifying the expression

\[
\left(\frac{12x^5 y^4}{4x^8 y^{-1}}\right)^2
\]

You entered:

\[
3x^{-8}y^5
\]

However, the feedback suggests that the powers must be positive, meaning your result contains a negative exponent that needs adjusting. Let's go step-by-step through the simplification process:

### Step 1: Simplify the fraction inside the parentheses.
Start by simplifying the expression inside the parentheses.

\[
\frac{12x^5 y^4}{4x^8 y^{-1}}
\]

1. Simplify the coefficients: 
   \[
   \frac{12}{4} = 3
   \]
   
2. Simplify the \(x\)-terms by subtracting exponents:
   \[
   \frac{x^5}{x^8} = x^{5-8} = x^{-3}
   \]

3. Simplify the \(y\)-terms by subtracting exponents:
   \[
   \frac{y^4}{y^{-1}} = y^{4-(-1)} = y^{4+1} = y^5
   \]

So, after simplifying, we get:

\[
3x^{-3}y^5
\]

### Step 2: Square the result.
Now, square the entire simplified expression:

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

1. Square the coefficient:
   \[
   3^2 = 9
   \]
   
2. Square the \(x\)-term:
   \[
   (x^{-3})^2 = x^{-6}
   \]
   
3. Square the \(y\)-term:
   \[
   (y^5)^2 = y^{10}
   \]

So, the final simplified expression is:

\[
9x^{-6}y^{10}
\]

### Step 3: Ensure positive exponents.
To make all the exponents positive, write \(x^{-6}\) as \( \frac{1}{x^6} \):

\[
\frac{9y^{10}}{x^6}
\]

This is the fully simplified expression with all positive exponents.
