I ran across these two notations for the log function (squared), which one is **more** conventional.

$\log^2(n)$ or $[\log(n)]^2$

Most people will use $\log^2(n)$ and there is no problem with that. If you want to be absolutely certain no one will think you are talking about $\log\log n$, then you can write $\bigl(\log(n)\bigr)^2$
