If you rewrite it, it becomes             (      −      1              )        2              3  .  (  −  1      )    2    =  1 and       1    3    =  1So positive 1.

x    y   is not defined for negative x and real y. Otherwise, we would have   (  −  1      )          1              /            3        =  −  1, but   (  −  1      )          2              /            6        =  1
