Combining a slider and superscript

[nemean]

I would like to animate a number going from 10^1 to 10^10, by having the exponent count from 1 to 10.

I have a slider going from 1 to 10 and then set the source text with an expression.

But then I can't set this exponent to be in superscript.

How do I do this?

You don't. You simply split up the layers and animate them separately. Superscript is a text decoration to begin with and most fonts only offer hard-coded glyphs for power of 2 and 3, anyway, so beginning with 4 any automatic formatting would fail in most cases.
