# General Power Rule of Integration

General Power Rule of integration is another important formula of integration. And this rules need derivative of the given function within the problem.

The general power rule of integration is of the form

Now consider

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

Here implies that

Multiplying and dividing by the given integral, we have

Using general power formula of integration, we have
