Homework Statement
Indefinite Integral (x^3)(e^x)
Homework Equations
The Attempt at a Solution
I know I need to substitute t=x^2
t^(3/2)e^sqrt(t)
U=e^sqrt(t)
du=e^sqrt(t) dt
dv=t^(3/2)
V= (5/2)t^(5/2)
Because it has an exponential function, I know I need to use the trick of running parts twice and then setting the two parts equal to each other, but I'm stuck.
Thanks for your help
