Last night I did about 30 integration problems that were practice for my upcoming exam. Ironically, the only one I could not get seems to be the easiest one, but I just can't do it. I don't see a method of substitution, and I've tried integration by parts (though it's not my specialty), so I don't know what to do. Any help would be greatly appreciated. Thanks!
It's a definite integral, I don't know how to write it in this forum. It's from 0 to 5:
