exponentiation - Negative Number raised to fractional power

How would you solve a negative number raised to a fraction a/b if b is odd and a is evem?
Ignoring imaginary numbers



i.e (1)23 Calculator returns an error



(1)13(1)13 = -1.-1 = 1 (By law of indices)



or




(113)2 = 1



or



(12)13 = 1



What about for other cases of a and b?
