Problem:
Compute
$\left(
\begin{array}{ccc}
 -\frac{5}{2} & -1 & \frac{3}{2} \\
 2 & -\frac{3}{2} & -3 \\
 \frac{5}{2} & -1 & 0 \\
\end{array}
\right)^3$.
Answer:
$\left(
\begin{array}{ccc}
 -\frac{135}{8} & -11 & \frac{9}{2} \\
 64 & \frac{25}{8} & -33 \\
 \frac{71}{2} & 3 & -\frac{75}{8} \\
\end{array}
\right)$
