Okay. I understand why to confuse with different terms, but so i think this is a UI issue.
Variables and code parts are always stated as grey. So it is just normal to assume power as variable instead of exponent.

So better to show the instruction like this?

Replace the ___s with the parameters base and exponent and call power on a base of 37 and a power of 4.

I mean, you already preset > result = base**exponent
