It all seems to have come about due to a rather pedantic disagreement
about the order of precedence of the ^ operator. Rather than just pick a
precedence order and tell anyone who wanted a different order to just
live with it, the ^ operator got ditched.

a*b^c*d might mean different things depending on the order in which the
operators are applied, but with pow() you write a*pow(b^c)*d or
pow(a*b,c*d) and there's no ambiguity.
