Quick Answer
1. Тригонометрическая форма: \( z = 2\sqrt{3} \left( \cos\frac{\pi}{3} + i \sin\frac{\pi}{3} \right) \).
2. Показательная форма: \( z = 2\sqrt{3} e^{i\frac{\pi}{3}} \).
3. \( z^3 = -24\sqrt{3} \).
4. \( \sqrt[3]{z} \) имеет три значения, которые можно найти с помощью формулы для нахождения корней.
5. Числа \( z, z^3, \sqrt[3]{z} \) можно изобразить на комплексной плоскости.
