expression1 ^ expression2 ⇒ ⇒ ⇒ ⇒ expression
list1 ^ list2 ⇒ ⇒ ⇒ ⇒ list
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.

squareMatrix1 ^ integer
⇒ matrix
Returns squareMatrix1 raised to the integer power.
squareMatrix1 must be a square matrix.
If integer = ë 1, computes the inverse matrix.
If integer < ë 1, computes the inverse matrix to an
appropriate positive power.
