# Applying the General Power Rule In Exercises 9-34, find the indefinite integral. Check your result by differentiating. See Examples 1, 2, 3, and 5. ∫ 4 x 2   -   5 ( 8 x )   d x

To determine

To calculate: The value of the provided indefinite integral 4x25(8x)dx.

Explanation

Given Information:

The provided indefinite integral is 4x25(8x)dx.

Formula Used:

According to the general power rule for integration,

If u is a differentiable function of x, then

undu=un+1n+1+C,

where n1

Calculation:

Consider the indefinite integral say I,

I=4x25(8x)dx

Above integral can be written in rational exponent form as;

I=(4x25)12(8x)dx

Let

4x25=u … (1)

Differentiate the above equation with respect to x;

ddx(4x25)=dudxddx(4x2)ddx(5)=dudx8x=dudx

Or

(8x)dx=du … (2)

Substitute the values of 4x25 and (8x)dx from equations (1) and (2) respectively in the provided integral;

I=u12<
