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

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

- Is there a recommended symbol for “equal by abuse of notation”?
- How did the notation “ln” for “log base e” become so pervasive?
- Why is $\frac{d^n}{dx^n}(y(x))$ the notation for the $n$th derivative of $y(x)$, instead of $\frac{d^n}{d^nx}(y(x))$?

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 $\bigl(\log(n)\bigr)^2$
