Take a look at the photos you upload before you finalize your post, I can't even read them because they're too small...

Sorry, I did ^3/2, it should have been ^1/2, just do the same steps and it should come out.. hah. Do you get a maxiumum number of tries before you fail the question?
For the other one, look up and really learn integration by parts, because you'll have to know how to do that for sure for any midterms/exams you have. |

1) switch bounds of integration twice so it becomes 0<x<20. Then use substitution calculate integral.
2) regular integration by parts in form of xe^-ax and distributive property of integral
