Returns the first argument raised to the
power of the second argument.
For a list, returns the elements in
list1
raised
to the power of the corresponding elements
in
list2
.
In the real domain, fractional powers that
have reduced exponents with odd
denominators use the real branch versus the
principal branch for complex mode.
