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.
