I just wanted to make sure a few of these problems were right.
1) (25x^-6 y^2) ^ 1/2 = SqRt [ 25x^-6 y^2 ] = 5x^-3 y = 5y/x^3
2) ( 8a^-3 b^9)^ 2/3 = CubedRt of [8^2] a^-2 b^6 = 4a^-2 b^6= 4b^6/a^2
3) ([16z^4] / [25x^8])^ -1/2 = {[16^-1/2] [z^-2]} / {[25^-1/2] [x^-4]} = [5x^4] / [4z^2]
Are these correct?
