To say that

	  1              2       b/c      th         b
	-1 = sqrt( ( -1 )  )    a    ==  c  root of a

is only partially correct.  There are n values for the nth root of any
number (not all of which might be real, e.g. cube roots of 1). Thus, we
don't have a one-to-one mapping between (bth. root of a) and
((bth. root of a) to the bth. power).
