文档中文本旁边的 Tikz 图片

Question

我正在使用 minipage 环境尝试将复数的八个 8 次方根放到一个 tikz 图形旁边，该图形以正八边形的形式表示这些根。

我的代码是：

\begin{minipage}{0.5\linewidth}
\begin{enumerate}
\item $\omega_8^0=\sqrt[8]{8} e^{-i\pi/24}$
\item $\omega_8^1=\sqrt[8]{8}e^{5i\pi /24}$
\item $\omega_8^2=\sqrt[8]{8}e^{11\pi i/24}$ 
\item $\omega_8^3=\sqrt[8]{8}e^{17\pi i/24}$ 
\item $\omega_8^4=\sqrt[8]{8}e^{23\pi i/24}$ 
\item $\omega_8^5=\sqrt[8]{8}e^{-19\pi i/24}$
\item $\omega_8^6=\sqrt[8]{8}e^{-13\pi i/24}$
\item $\omega_8^7=\sqrt[8]{8}e^{-7\pi i/24}$
\end{enumerate}
\end{minipage}

然而，当它编译时，它看起来像这样：

有人能帮帮我吗？谢谢 :)
