Quick Answer
1. Модуль \( z \): \( |z| = 2\sqrt{3} \)
2. Аргумент \( z \): \( \theta = \frac{\pi}{3} \)
3. Тригонометрическая форма: \( z = 2\sqrt{3} \left( \cos\frac{\pi}{3} + i \sin\frac{\pi}{3} \right) \)
4. Показательная форма: \( z = 2\sqrt{3} e^{i\frac{\pi}{3}} \)
5. \( z^3 = -24 \)
6. \( \sqrt[3]{z} \) зависит от значения \( k \) и имеет три различных значения.
