I'd be more interested, and better able to help, were you able to do your work on paper, photograph it and then upload the image here.  Otherwise I'd need to do the entire problem from scratch myself.  Just don't have the time for that.

Integration by parts:  Int (u dv) = uv - Int (v du), right?

What did you choose for u?    What is your du?
what did you choose for dv?  What is your v?

that might be a good idea :)
just to see how you approached this.

I came out with an exact solution but I'll punch it real quick and see if it matches your decimal value.
