 Let $\alpha\in \C$.
 
 \begin{itemize}
 \item [1.] Find the explicit formula for the elements of the matrix $A_n = \begin{pmatrix}\alpha &1\\ 0 &\alpha\end{pmatrix}^{n}$, where $n \geq 1$ is an integer. Show the formula by reccurance.
  \item [2.] Let $\alpha = 1+\textrm{i}$. Calculate $\alpha^{99}$ and $\alpha^{100}$.
  \item [3.] Calculate  $\begin{pmatrix} 1+\textrm{i} &1\\ 0 &1+\textrm{i}\end{pmatrix}^{100}$.
