Find the argument
$$\begin{align} &A. \left(\frac{\sqrt{3}}2+\frac i2 \right)^7 \\ &B. (11 − i 11\sqrt{3})^9 \end{align}$$
I get $\frac{7\pi}6 +2kπ$ for A. I just want to make sure that I am doing this right. I also believe that argument and Argument are two different concepts. In this case argument is being used.
