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

(-2/3)^3= (-2/3)(-2/3)(-2/3) = -8/(27)

for negative it will be

reciprocal of above...however it should be remember that just multiply at the rate which is exponent. and - - = +, - + = -
