Your question is very unclear but I assume from the tag you are using beamer.
\documentclass{beamer}
%\usepackage[T1]{fontenc}
%\showoutput
\begin{document}
\begin{frame}
\textbf{aaa\textbackslash}
aaa \textbackslash
\end{frame}
\end{document}
Produces the warning
LaTeX Font Warning: Font shape `OMS/cmss/bx/n' undefined
(Font) using `OMS/cmsy/m/n' instead
(Font) for symbol `textbackslash' on input line 11.
Telling you that \ comes from the math sans serif and there is no bold in OT1 encoding.
Adding
\usepackage[T1]{fontenc}
The warning goes away and you get:
where if you look closely (or at the output from \showoutput) the \ is bold.
Best Answer
Either simply within the
verbatimenvironment or more sophisticated with the listings package.
