We will rewrite that as du = 6r? dr. Our goal is now to rewrite the entire integral in terms of our new variable u and its derivative du. Since du = 6x2 dx and our integrand includes r? dr, we will write - du = x² dx. So we can rewrite the integral as follows: |7(2° + 3)° dr = du. This new integral is one that we can do easily. Complete this integral, getting an answer in terms of u.

5. We will rewrite that as du = 6x² dx. Our goal is now to rewrite the entire integral in terms of
our new variable u and its derivative du. Since du = 6x2 dx and our integrand includes r? dr,
we will write du = x² dx. So we can rewrite the integral as follows:
1
(2x³ + :
u³ du.
This new integral is one that we can do easily. Complete this integral, getting an answer in
