\(2\sqrt{3}\) . [cos ( \(\frac{\pi}{3}\) ) +i.sen \(\frac{\pi}{3}\) ) ]

\(2\sqrt{3}.\) [cos( \(-\frac{\pi}{3}\) )+i.sen( \(-\frac{\pi}{3}\) )]

\(2\sqrt{3}.\) [cos ( \(\frac{2\pi}{3}\) )+i.sen( \(\frac{2\pi}{3}\) )]

\(-2\sqrt{3}.\) [cos ( \(\frac{\pi}{3}\) )+i.sen ( \(\frac{\pi}{3}\) ) ]

\(-2\sqrt{3}.\) [cos (- \(\frac{2\pi}{3}\) ) +i.sen (- \(\frac{2\pi}{3}\) ) ]
