**(-27) to the negative 4/3 power**

**Answer:**

First you remove the negative from then power by getting the reciprocal to -27 which is 1/(-27^4/3) then to get rid of the fraction in the power you find the cube root of -27 which is -3 so you have 1/(-3^4) then you just solve -3^4 to get 81 so the final answer is 1/81.
