Kind of tired of people in the programming community proudly complaining about not knowing simple math notation. Educate yourself. Everyone else in the engineering world knows these basic math notations.
Anyone targeting their work at non-experts should explain even what seems like trivial notation to them since they can't know what other meanings the reader may think the notation holds.
Computer languages benefit from the fact that poorly designed syntax can be deprecated (not in all cases, e.g. C++) by introducing new features to the language.
Notation in math never advances in the same way for some reason.
Specifically for the superscript case, the vast vast vast majority of the cases, it will be obvious whether the superscript notation means exponentiation or indexing. When there are ambiguities, what the person explaining the equation should do is clarify the ambiguity.
It doesn't do the world any good to make the entire engineering world learn (relatively) obscure programming languages in order to be slightly more clear (and let's not forget, much more verbose) when writing down simple equations, when all one has to do is clarify a couple of ambiguities when writing down equations.
Let me make it very clear and say this: equations are meant to explain things. They are not standalone pieces of code that you can copy and paste into a REPL. They are tools to explain how something works. You should always have accompanying text that explains what all the variables in the equation mean and clarify unclear notations.
