How to represent ln^2(x) in Java?  

Math.log(x) would work for just ln(x) but how do I do ln^2(x)?

It is not ln(subscript(2))x it is ln^2(x).  See image.  This is different right?

So, would this work?  Math.pow((Math.log(x), 2));

If what you need is natural log squared, then yes

If by ln^2(x), you actually mean ln(ln(x)), this would be Math.log(Math.log(x))

If you mean (ln(x))^2 = ln(x) * ln(x), this would be Math.pow(Math.log(x),2), as a number of people have indicated.

The notation itself can be ambiguous.  It would help if we knew the context.

Additionally, in some contexts, log(x) is understood to be the natural log, ln(x).  In others, it is understood to be base 2, or even base 10.
