subscript and superscript in same variable name

[relayman357]

I'm trying to figure out how to create a math variable name that includes both subscript and superscript characters like below:

The subscript is no problem, how do I get the superscript portion?

Not just in a way that will let me display this text, but will allow me to use this exact variable later for calculations.

Simple and short answer: you don't. 😞

Prime does not offer literal superscripts.

Well, you might be able to, but it's not simple and it's very limited!  I found (in the character map, a superscripted "a". Alt-0170.  If I launch a text window in Prime (ctrl-T, and paste in a super scripted word, then  move down and type := to start a math region I can paste the text in for the variable name, and subscript it if desired. 

But it's a lot of effort for what you want.
