Ok how shall i go about this one.. I = (x^2)*(e^(x^3)) I know the rule: I = f(x)^n*f'(x)dx = 1/n+1*f(x)^(n+1) + C I cant quite see how it fits with this particular problem.. Can anyone help...

I think it would be quite clear if you substituted $\displaystyle u=x^3$, $\displaystyle du=3x^2~dx$
Ah that was alot easier than I thought This is the rule I needed... I = f'(x)*e^f(x)dx = e^(f(x)) + c Thanks alot
