The expression provided is:

\[
\left( \frac{3a^2}{b^3} \right)^2
\]

We are tasked with simplifying this.

### Step-by-step solution:
1. Apply the power rule: \(\left(\frac{x}{y}\right)^n = \frac{x^n}{y^n}\). This gives:
   \[
   \frac{(3a^2)^2}{(b^3)^2}
   \]

2. Simplify the numerator and denominator:
   - \( (3a^2)^2 = 3^2 \cdot (a^2)^2 = 9a^4 \)
   - \( (b^3)^2 = b^{6} \)

Thus, the expression simplifies to:

\[
\frac{9a^4}{b^6}
\]

### Final Answer:
The correct simplified expression is:

\[
\boxed{\frac{9a^4}{b^6}}
\]

Looking at the options provided in the image, this matches the third option.

Here are five related questions to deepen your understanding:
1. What is the general rule for simplifying powers of fractions?
2. How does the exponent rule \((a^m)^n = a^{mn}\) apply to both numerators and denominators?
3. How would the simplification change if the exponent were negative?
4. Can you apply this technique to an expression like \(\left(\frac{5x^3}{y^2}\right)^3\)?
5. How does this method differ when variables are in both the numerator and denominator?

**Tip:** When simplifying expressions with exponents, apply the exponent to both the numerator and denominator separately before combining terms.
