Trying to integrate x raised to e power
I can't seem to figure this out. I did not learn properties of logs in college algebra very well, and I think that might be part of why I'm stumped.

Question is: find the anti-derivitive of x^2e + e^x dx. I can integrate e^x dx by simply using rules of integration, but I'm stuck on x^2e dx.

Dont for get e is a constant

So the power rule tells us that

$\displaystyle \int x^{n}dx=\frac{x^{n+1}}{n+1}$

so

$\displaystyle \int x^{2e}dx=...$

e is just a constant. Raise the power and divide by that power.

Edit: Guess i'll cut out the answer, then.

GAH, that's what i started to do and talked myself out of it. Thanks for your quick replies!
