The formula @expr{x^0} is simplified to @expr{1}, or to @samp{idn(1)}
in Matrix mode. The formula @expr{0^x} is simplified to @expr{0}
unless @expr{x} is a negative number or complex number, in which
case the result is an infinity or an unsimplified formula according
to the current infinite mode. Note that @expr{0^0} is an
indeterminate form, as evidenced by the fact that the simplifications
for @expr{x^0} and @expr{0^x} conflict when @expr{x=0}.
unless @expr{x} is a negative number, complex number or zero.
If @expr{x} is negative, complex or @expr{0.0}, @expr{0^x} is an
infinity or an unsimplified formula according to the current infinite
mode. The expression @expr{0^0} is simplified to @expr{1}.
Powers of products or quotients @expr{(a b)^c}, @expr{(a/b)^c}
are distributed to @expr{a^c b^c}, @expr{a^c / b^c} only if @expr{c}
