The integral of a constant is simply the constant multiplied by the variable of integration. For the integral of $5$, the result is:

$\int 5 \, dx = 5x + C$

where $C$ is the constant of integration.

Would you like more details on this concept, or do you have any further questions?

Here are 5 related questions:

1. What is the integral of a constant other than 5?
2. How does the constant of integration $C$ work in indefinite integrals?
3. What is the difference between indefinite and definite integrals?
4. Can you integrate a function with respect to other variables besides $x$?
5. What is the role of the constant when solving definite integrals?

Tip: When integrating constants, remember that you're essentially multiplying the constant by the variable and adding the constant of integration, $C$, to account for all possible antiderivatives.
