# Evaluate the integrals in Problems 1-32. ∫ x 3 e 3 x 4 d x

To determine

To calculate: The value of the integral x3e3x4dx.

Explanation

Given Information:

The provided integral is x3e3x4dx.

Formula used:

If u is a function of x, then:

euudx=eudu=eu+C

Calculation:

Consider the provided integral:

x3e3x4dx

Rewrite the integral by multiplying and dividing by 12 as:

11212x3e3x4dx

Now, consider u=3x4.

Then, the above integral became as,

11212x3eudx

Now, use the formula of integral:

euudx=eu<
