Question
**Problem Statement:**

Find the derivative of the function below. Use lower case letters.

\[ p(y) = ay \cdot e^{by} \]

\[ \frac{dp}{dy} = \boxed{} \]

**Explanation:**

The task is to calculate the derivative of the given function with respect to \( y \). The function \( p(y) \) is the product of two functions, \( ay \) and \( e^{by} \), and will require the use of the product rule for differentiation. 

The product rule states: if \( u(y) \) and \( v(y) \) are functions of \( y \), then the derivative of their product \( u(y) \cdot v(y) \) is given by:

\[ \frac{d}{dy}[u(y) \cdot v(y)] = u(y) \cdot \frac{dv}{dy} + v(y) \cdot \frac{du}{dy} \]

**Solution Outline:**

1. **Identify the Functions:**
   - \( u(y) = ay \)
   - \( v(y) = e^{by} \)

2. **Differentiate Each Function:**
   - \( \frac{du}{dy} = a \) (derivative of \( ay \) with respect to \( y \))
   - \( \frac{dv}{dy} = be^{by} \) (derivative of \( e^{by} \) with respect to \( y \))

3. **Apply the Product Rule:**
   - \( \frac{dp}{dy} = ay \cdot be^{by} + e^{by} \cdot a \)

4. **Simplify:**
   - \( \frac{dp}{dy} = aby \cdot e^{by} + ae^{by} \)

This gives the derivative of the given function.
