It looks like you might be trying to type a LaTeX expression or command. LaTeX is a typesetting system that is widely used for producing scientific and mathematical documents due to its powerful handling of formulas and bibliographies.
If you could provide more context or specify the LaTeX expression or command you're interested in, I can help you with it. For example, if you want to write a simple mathematical expression like "e(iπ) + 1 = 0", you would type:
```latex
e(ipi) + 1 = 0
```
And the rendered output would be:
$$
e{ipi
