# Evaluate the integrals in Problems 1-32. Identify the formula used. 6.   ∫ 4 ( 3 x ) d x

To determine

To calculate: The value of the integral 43xdx.

Explanation

Given Information:

The provided integral is 43xdx

Formula used:

For any variable u, the integral formula is,

audu=aulogae+C=aulna+C

Where, ‘a’ is not a function of u. and C is the constant of integration.

Calculation:

Consider the provided integral,

43xdx

The integral is similar to that of the integral formula,

audu

Therefore, the formula used is audu=aulogae+C=aulna+C
