That's pretty basic arithmetic. What was causing you difficulty?

(2/3)^3= (2/3)(2/3)(2/3) = 8/27 Therefore the negative of this result is 8/27. This number is not the negative of an exponent. Maybe you are asking about the negative of the exponent 3 in the expression. In that case you would have (2/3)^3 = (3/2)(3/2)(3/2) = 27/8
