2) Express the complex number $\displaystyle 2+2\sqrt{3}j$ in the form re^{j\theta} hence obtain the cartesian form of $\displaystyle (2+2\sqrt{3}j)^6$
This is what i have attempted:
I found out that $\displaystyle 2+2\sqrt{3}j = 4e^{\frac{\pi}{3}j}$
hence i make $\displaystyle (2+2\sqrt{3}j)^6 = (4e^{\frac{\pi}{3}j})^6$
what would i do next?
P.S
