Question (4 points): Consider two matrices A=\left[\begin{array}{lll} 1 & 2 & 0 \\ 3 & 1 & 2 \end{array}\right] \text { and } B=\left[\begin{array}{cc} 2 & 1 \\ 1 & 1 \\ -1 & 3 \end{array}\right] \text {. The matrix } \left[\begin{array}{cc} 3 & -3 \\ 0 & 10 \end{array}\right] \left[\begin{array}{cc} 3 & 0 \\ 5 & 10 \end{array}\right] \left[\begin{array}{cc} 4 & 5 \\ 3 & 10 \end{array}\right] \left[\begin{array}{cc} -5 & 5 \\ 0 & 10 \end{array}\right]
