How to write apostrophe after s in latex [closed]

Question

I have tried \' or $'$ but the apostrophe after s does not appear in Latex. Do you know how can I do it?

Answer 1

What do you mean? Both kinds of apostrophes (sorry if that's not the correct typographical name) show up in both normal and math mode. (Not an answer, but typesetting needed for question.)

\documentclass{article}

\begin{document}
A'B'C

A`B`C

$A'B'C$

$A`B`C$
\end{document}

(This would perhaps be a better question on the TeX stackexchange group.)
