Sign of fractional exponent
What is the sign of 1 2 3 ? I thought it was positive 1 because it involves squaring, but that doesn't seem to be the case. Why?

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