    \[\int\limits_{}^{}[f(x)]^n f'(x) dx\] let u=f(x) => du=f'(x) dx so we have \[\int\limits_{}^{}u^n du=\frac{u^{n+1}}{n+1}+C=\frac{(f(x))^{n+1}}{n+1}+C\]

    \[\int\limits_{}^{}c f(x)dx=c \int\limits_{}^{}f(x) dx\]

    what ever you get when you integrate f just make sure it is all being multiply by c
