Question

Can someone please explain the solution to this indefinite integral? :)

Answer 1

I've been supplied the solution but I'm not sure how it works so an explanation would be great :)

Answer 2

u=3x+1
then du=3 dx
or solving for dx gives
1/3 du=dx

Answer 3

\[\int\limits_{}^{}u^5 \frac{1}{3} du \\ \frac{1}{3} \int\limits u^5 du\]

Answer 4

can you evaluate that ?
