To solve the given expression, let's first extract the expression from the image:

\[
\text{Simplify: } \frac{18x^2z^6}{3x^6z^2 \times 2x^5z^7}
\]

### Step-by-Step Simplification

1. **Combine the terms in the denominator:**

\[
3x^6z^2 \times 2x^5z^7 = (3 \times 2) (x^6 \times x^5) (z^2 \times z^7) = 6x^{11}z^9
\]

So, the expression now is:

\[
\frac{18x^2z^6}{6x^{11}z^9}
\]

2. **Simplify the coefficients (numerical part):**

\[
\frac{18}{6} = 3
\]

3. **Simplify the exponents using the quotient rule:**

- For \(x\): \(x^2 / x^{11} = x^{2 - 11} = x^{-9}\)
- For \(z\): \(z^6 / z^9 = z^{6 - 9} = z^{-3}\)

4. **Combine everything:**

\[
3 \cdot x^{-9} \cdot z^{-3}
\]

5. **Express with positive exponents:**

\[
\frac{3}{x^9z^3}
\]

### Final Answer:

\[
\frac{3}{x^9z^3}
\]
