Hi all.I have been trying to use integration by parts for this question.

I have got as far as 3x^(1/3)*Ln(5x)-3 (int)x^(1/3)*1/5x.

Im a little stuck on the last bit of integration, i.e, (int)x^(1/3)*1/5x.

I cant see if their is a cancellation to simplify the last bit.

Am i using the correct rule? Can anyone help????

Thanks.
