Integration of any constant of power is another important integral calculus; this integral belongs to exponential formulas category and is one of the simplest formula of integration.

The integration of constant of power x is of the form

Where is any constant and not must be not equal to zero.

Now consider

Using the derivative formula , we have

Integrating both sides of equation (i) with respect to , we have

Since integration and differentiation are reverse processes to each other , so the integral sign and on the right side will cancel each other, i.e.

__Example__**:** Evaluate the integral with respect to

We have integral

Using integral formula , we have
