The number of different matrices that can be formed with elements 0, 1, 2, or 3 each matrix having 4 elements, is

The matrix will be of the order 4×1 or1×4 or 2×2 . For each order, the number of different matrices = the number of ways to fill places by 0,1,2,3=4×4×4×4 .∴ Required no. of matrices=3×44
