(i) If a matrix has 4 elements, what are the possible order it can have?
(ii) If a matrix has 8 elements, what are the possible orders it can have?
Please give a detailed solution of these questions of Matrices chapter from ML AGGARWAL
We know that if matrix is of order m × n, it has mn elements, we will find all ordered pairs of natural numbers, whose product is 8.
Thus, all possible ordered pairs are (1, 8), (8, 1), (4, 2), (2, 4)
Hence, possible order are 1×8,8×1,4×2,2×4
