-1/1 = -1/1
-1/1 = -1/1(-1/-1)

(-1/1)^.5 = (1/-1)^.5
((-1)^.5) / (1^.5) = (1^.5) / ((-1)^.5)
cross multiply, and you get
((-1)^.5) * ((-1)^.5) = (1^.5) * (1^.5)
-1 = 1
discuss that one why don't ya

square rooting then squaring again cause a loss of information. consider:
x = 3, y = -3
x^2 = y^2
sqrt(x^2) = sqrt(y^2) sqrt = square root of
however, x != y even though sqrt(x^2) = x and sqrt(y^2) = y and sqrt(x^2) = sqrt(y^2).
