Multiplying both sides by the denominator, we get:

(z + 4)(1)(1)/(3)(1)(0) = -4

Simplifying, we get:

(z + 4)/3 = -4

Multiplying both sides by 3, we get:

z + 4 = -12

Subtracting 4 from both sides, we get:

z = -16

Thus, the solution is z = -16, which corresponds to choice C. None of the other choices are correct.

Solve. (Z + 4)1/3 = -4
