(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Use substitution to find: (3x^2)*(e^2x^3)*(dx)

I don't know how to do the integration sign...

2. Relevant equations

3. The attempt at a solution

u=2x^3

du=6x^2

this is where I got confused, my teacher isn't that good and I'm trying to understand how to substitute...

I know that its supposed to be e^u*du=e^u+c

the answer was (e^2x^3)/2+C
