Negative exponent in note

I’m trying to get C^-1 to type up in latex in a note. My code is:

content: “What is C\\^${-1}(625)? What does it represent in this situation?”

When I hit preview, the negative is superscript, but the 1 isn’t. How do I get both the negative sign and the number 1 in the exponent?

I figured it out.
content: “What is C\\^{{-}1}(625)?..” works
