alphabet "a" in latex

Question

How to write alphabet "a" in latex?

I am writing equations

but I want "a" to look like this?

well there are millions of fonts, I can't guess exactly which one is used in your image and every font will look slightly different but does it matter, it's just an a, do you also need the square full stop not a round one? — David Carlisle, Jun 23 '23 at 14:36
so you have added an image which makes it clear you have selected a non standard math font, so the answer is, in code you have not shown do not do whatever you did, so you get the default. It is hard to tell people how to change unseen code — David Carlisle, Jun 23 '23 at 14:41
@Jonathan In the future, please always include a small, but compilable test file in your questions. This way we don't have to guess the class you use based on the colour of your bullet points ... — samcarter_is_at_topanswers.xyz, Jun 23 '23 at 14:47

By default, beamer uses a sans serif font for math. If you prefer serif font, you can use \usefonttheme[onlymath]{serif}:

\documentclass{beamer}
\usefonttheme[onlymath]{serif}
\begin{document}
\begin{frame}
[
a^n
]
\end{frame}
\end{document}
