This is doing my head in!(adsbygoogle = window.adsbygoogle || []).push({});

I split it to 1/x * 1/log(x) and got the intergral = 1 + the intergral when using intergration by parts.

I know the answer is log[log(x)] but have no idea how you get log of a log.

Got a feeling the answer is going to really obvious!
