My old statistics lecturer would write x-¹ as shorthand meaning everything that is not x, I thought it was in more common usage but perhaps not. I know it more generally means the reciprocal, he just expected you to know which he meant by context.

x-¹ Where I come from, that’s read as “x to the [power of] minus one”. “x minus one” is, well, x - 1. Not the same thing at all. (I admit, my chances of deciphering what you meant might not have been all that high even if you’d used the correct phrasing, but without it, the chance was zero.)
