Firstly, this isn't calculus, this is algebra. In the future, please don't mistag your posts. \ \ For convenience, I'll call $z=-\frac{11\sqrt 3}{2}+\frac{11}{2}i$. \ \ We know that $|z|=\sqrt{\left(-\frac{11\sqrt 3}{2} \right)^2+\left(\frac{11}{2} \right)^2}=11$. \ \ Furthermore, the argument of $z$ is $\frac{5\pi}{6}$, which can be verified by sketching a diagram and observing the argument is $\pi-\arcsin \left(\frac{1}{2} \right)$. \ \ \ So, we need to find $(11e^{5i\pi/6})^{1/4}$, which is $11^{1/4}e^{\frac{5i\pi}{24}}$.
