Though probably non-standard in typesetting, one might make a slight typographic difference between π₯Β²β and π₯βΒ² by letting the sub- or superscripts that come later partially, but not fully, to the position of the one that comes before. For example, π₯βΒ² might mean the square of π₯β, and π₯Β²β the component 0 of π₯Β², not necessarily the same. Traditionally, such things are left for the reader to interpret.
Isn't that poor nomenclature, being ambiguous? I would explicitly write (π₯β)Β² or (π₯Β²)β in such cases, and I have also seen π₯Β²|β used for example, or other non-ambiguous shorthands. Alan
