Another integral q

[dangerman77]

Can anyone give me a clue as how to approach this?

(The answer is

but how do I get there?)

The antiderivative of log(x) is given by:
\(\displaystyle \L
\int {\log (x)dx = x\log (x) - x}\).

So for problem just do integration by parts twice.

Thanks pka! I appreciate the quick (and helpful!) response.
