The image you uploaded contains a calculus problem regarding the derivative of a product of functions. The problem is in French and is titled "Dérivée d'un produit," which translates to "Derivative of a product." The task involves calculating the derivative of a function that is the product of two other functions.

Here’s a general breakdown of how to solve such a problem:

### Product Rule for Derivatives
If you have two functions, say \( u(x) \) and \( v(x) \), the derivative of their product is given by the product rule:

\[
\frac{d}{dx} [u(x) \cdot v(x)] = u'(x) \cdot v(x) + u(x) \cdot v'(x)
\]

This means that you take the derivative of the first function (\( u'(x) \)) and multiply it by the second function \( v(x) \), then add the product of the first function \( u(x) \) and the derivative of the second function \( v'(x) \).

### Problem Breakdown
1. Identify the two functions \( u(x) \) and \( v(x) \) from the product given in the problem.
2. Differentiate each function individually.
3. Apply the product rule by multiplying the derivative of the first function by the second, and then adding the product of the first function and the derivative of the second function.

### Example
If the problem provides a function \( y(x) = x^2 \cdot e^x \), where \( u(x) = x^2 \) and \( v(x) = e^x \):

1. Differentiate \( u(x) = x^2 \):
   \[
   u'(x) = 2x
   \]
   
2. Differentiate \( v(x) = e^x \):
   \[
   v'(x) = e^x
   \]

3. Apply the product rule:
   \[
   y'(x) = u'(x) \cdot v(x) + u(x) \cdot v'(x)
   \]
   \[
   y'(x) = 2x \cdot e^x + x^2 \cdot e^x
   \]
   \[
   y'(x) = e^x(2x + x^2)
   \]
