$$\mathbf { A } = \left( \begin{array} { l l }
2 & 0
5 & 3
\end{array} \right) , \quad \mathbf { B } = \left( \begin{array} { r r }
- 3 & - 1
5 & 2
\end{array} \right)$$
- Find \(\mathbf { A B }\).
Given that
$$\mathbf { C } = \left( \begin{array} { r r }
- 1 & 0
0 & 1
\end{array} \right)$$ - describe fully the geometrical transformation represented by \(\mathbf { C }\),
- write down \(\mathbf { C } ^ { 100 }\).
