Use the following matrix to perform the indicated operation, when possible. (If not pos. matrix.) \[ A=\left[\begin{array}{lll} 3 & 1 & 0 \\ 4 & 2 & 3 \\ 0 & 2 & 3 \end{array}\right] \] Find \( A^{2} \). 4. Your matrix does not have the appropriate number of rows and columns. [0/1 Points] HARMATHAP12 \( 3.2 \). Use the following matrix to perform the indicated operation, when possible. (If not pos matrix.) \[ C=\left[\begin{array}{ll} 7 & 9 \\ 4 & 1 \end{array}\right] \] Find \( C^{3} \) Use the following matrices to perform the indicated operation, when possible. (If not pi the matrix.) \[ D=\left[\begin{array}{ll} 8 & 6 \\ 3 & 7 \end{array}\right] \quad E=\left[\begin{array}{lll} 1 & 0 & 3 \\ 7 & 1 & 0 \end{array}\right] \] Find \( D E \).
