### What is log² x?

**Mon Apr 03, 2017 4:23 am UTC**This came up in Computer Science : Deliberately Bad Algorithms, and I'm wondering what people think is correct.

I was going to put an undecided/depends on context option, but have decided that that would be a bad idea; choose which one you think is more correct.

It's clearly log(log x).

As a side note, I believe most people interpret

- sin
^{2}(x) as (sin(x))^{2}and not sin(sin(x)) - sin
^{-1}(x) as arcsin(x) and not csc(x). - log
^{-1}(x) as exp(x) = e^{x}and not 1/log x - f
^{n}(x) as f(f(... (f(x)...)) and not (f(x))^{n}.
