Why the following piece of Org Mode document doesn't display correctly
when exported to a PDF document via LaTeX?
\[n!=
\begin{cases}
1 & n=0 \\
n(n-1)! & n\ge 1 \\
\end{cases}
\]
It is displayed at the left instead of center of the document.
Moreover the \[ and \] symbols are not removed in the final document.
I can fix the problem by replacing \[ and \] with \begin{displaymath}
end \end{displaymath} respectively:
\begin{displaymath}
n!=
\begin{cases}
1 & n=0 \\
n(n-1)! & n\ge 1 \\
\end{cases}
\end{displaymath}
Is this the best way to fix the problem? Am I missing a better solution?

The \[ ... \] construct is only valid, in org, if on a single
line. Your solution is perfectly valid although, in practice, I would
use equation* instead of displaymath.
Alternatively, you can enclose it all in a export block, as in
#+begin_export latex
\[
...
\]
#+end_export

The following code doesn't work:
#+begin_export latex
\[
n!=
\begin{cases}
1 & n=0 \\
n(n-1)! & n\ge 1 \\
\end{cases}
\]
#+end_export
Because of the following error message:
> ! LaTeX Error: Environment export undefined.
But I can use #+begin_latex and #+end_latex instead.
I read the former syntax is new and will be released with Org Mode 9.0.
Is that true?

Yes, indeed. I forgot to ask what version of org you were using!
I'm glad the old format works for you.

I forgot to thank you for the help! :)
