**Problem 17: Integration of a Polynomial Exponential Product**

Evaluate the integral:

\[ \int x^4 e^x \, dx \]

This integral involves the product of a polynomial \(x^4\) and an exponential function \(e^x\). Solving this typically requires the method of integration by parts and may involve multiple iterations due to the polynomial term.

This problem is typically encountered in calculus courses, particularly those covering techniques of integration. The integral belongs to a class of integrals that can be approached using the formula for integration by parts:

\[ \int u \, dv = uv - \int v \, du \]

where \( u \) and \( dv \) are parts of the original integrand.

For this specific integral, we would choose:

\[ u = x^4 \quad \text{and} \quad dv = e^x \, dx \]

Calculating each part individually:

\[ du = 4x^3 \, dx \quad \text{and} \quad v = e^x \]

Then, applying integration by parts iteratively will progressively decrease the power of \( x \) until the integral involves only the exponential function, which simplifies easily.
