### Problem Statement:

**9)** \( y = 5x^2 e^{3x} \)

Select the correct derivative of the function from the options below:

**A)** \( 5xe^{3x}(2x + 3) \)

**B)** \( 10xe^{3x}(3x + 2) \)

**C)** \( 5xe^{3x}(3x + 2) \)

**D)** \( 10xe^{3x}(2x + 3) \)

### Explanation:

The problem asks for the derivative of the given function \( y = 5x^2 e^{3x} \). The options listed are potential derivatives of this function. The task involves identifying the correct option by applying the rules of differentiation, such as the product rule and the chain rule.

Here’s a step-by-step guide to find the solution:
1. Recognize that the function is a product of two functions: \( u = 5x^2 \) and \( v = e^{3x} \).
2. Apply the product rule: \( \frac{d}{dx}(uv) = u'v + uv' \).
3. Differentiate \( u = 5x^2 \) to get \( u' = 10x \).
4. Differentiate \( v = e^{3x} \) using the chain rule to get \( v' = 3e^{3x} \).
5. Substitute these derivatives into the product rule formula.

This solution will help find the correct option from A, B, C, or D.
