Problem:
Compute
$\left(
\begin{array}{ccc}
 5-3 i & -2+3 i & 2-4 i \\
 -4-4 i & 4-3 i & 4-4 i \\
 2-i & -3-4 i & -2+i \\
\end{array}
\right)^3$.
Answer:
$\left(
\begin{array}{ccc}
 316-406 i & 111+414 i & -28+22 i \\
 -532+188 i & 124-125 i & -284+44 i \\
 79+130 i & -102+181 i & 116+137 i \\
\end{array}
\right)$
