Intergral from 0 to 1 of (5x^4 * e^-x)dx

5x^4 * e^-x)dx

\(\displaystyle\int_0^1 (5x^4 * e^{-x})dx\\ \)

I did this with several applications of Integration by Parts.

I ended up with

\(\frac{-325}{e}-120\) but I most likely made several careless mistakes along the way.

Just one careless mistake Melody, it should be \(-\frac{325}{e}+120\)

Well that wasn't so bad. Thanks Alan.
