(aka, the integral from 0 to 4 of the square root of x times e to the power of the square root of x, incase the above wasn't clear).

I've tried integration by parts, but each time I integrate the new integrand just aquires a higher power of x and this seems to go on indefinately. I've also tried a change of base to make the integral equal e^(sqrt(x) + ln(x)) but the same thing happens.

If anybody has any ideas on how to get around this, it would be wonderful.

Thank you
