MCQ
Solution
All of these
Explanation:
We know that if a matrix has mn elements, it is of order m × n. To find all possible orders of an 8 element matrix, we will find all order pairs of natural numbers whose product is 8.
Thus, all possible ordered pairs are (1, 8), (8, 1), (4, 2), (2, 4).
Hence, possible orders are 1 × 8, 8 × 1, 4 × 2, 2 × 4
