Rewrite with positive exponents assume that even roots are nonegative and that all demonintors are nonzero.
(6xy) 3

4
The parenthesis is supoose to be around the line as well as the four. I just don't know how to make my computer do that. This is what I get. Can some check to see if it is correct please???
(6xy)3

(4)as this should be in parenthesis too
(6xy)3
 (6x)3
y3 =
or 1
 3
216 x
xa=1/xa
or either this way ===>
1/216x^3
(6x/y)^3
(6x)^3
(1/6x)^3
1/216x^3

(6xy)^3 = 1 / (6xy)^3 = 6^3x^3y^3 =
216x^3y^3.
