The question:
Use a substitution to evaluate
My attempt:
Normally I'd check to see if value within the brackets is an anti-derivative of the element outside (chain rule). In this case, it isn't. I'm uncertain as to how I should go about finding a substitution. Any ideas? Thanks.

^{19}dx=\int{\frac{u+1}{5}u^{19}\frac{du}{5}=\fr ac{1}{25}\int{(u+1)u^{19}}du=\frac{1}{25}\int{\lef t(u^{20}+u^{19}\right)}du)
