Denominator of the power expression indicates the degree of the root in this case its the cubic root. Numeriator denotes the degree of power in this case squared. The negative sign means to inverse the base value. Applying these operations in a sequential order starting with the numeriator and then the squared we get: (4/25)^-1 Inversing the value then gives the answer: 25/4
