## Formatting question

### Formatting question

What is the standard (preferred) way to show a sub-scripted variable raised
to an exponent.  I run into these often in my equations, and have a number
of possible solutions, and was wondering what the rest of the world does.

$V_{infty}^2$
$V_{infty}\,^2$
$V_{infty}\ ^2$
$V_{infty}^{\,2}$
$V_{infty}^{\ 2}$
$V_{infty}^{\ \!2}$                <----possibly my favorite
$V_{infty}^{\ \!\!2}$

Hi!

The most elegant way to prefer may be the following:
$V_{\infty}{}^{2}$

I have written a book using latex.  I use pdflatex to generate
pdf files, works fine.  I want to give a book printer the pdf file to
print the book from.  Does anyone have experience with this,
is pdf an acceptable format for book printers ?  I heard that
"Quark Express" is the preferred format ?
