Question

If a matrix has 8 elements, what are the possible orders it can have? What if it has 5 elements?

Answer 1

We know that if a matrix is of order `m xx n` then it has mn elements.

The possible orders of a matrix with 8 elements are given below:
1 x 8, 2 x 4, 4 x 2 , 8 x 1 
 
Thus, there are 4 possible orders of the matrix.


The possible orders of a matrix with 5 elements are given below:
1 x 5, 5 x 1

Thus, there are 2 possible orders of the matrix.
