Question

If a matrix has 18 elements, what are the possible orders it can have? What, if it has 5 elements.

Answer 1

Given: a matrix has 18 elements.

To find: What are the possible orders it can have? What, if it has 5 elements.

Solution:

• Now we have know that order of matrix is m x n.

• So for 18, we have:

                  2 x 9, 3 x 6, 18 x 1, 1 x 18, 6 x 3, 9 x 2

• These are the possible orders.

• If matrix have 5 elements then order will be:

                  1 x 5 or 5 x 1

Answer:

             If a matrix has 18 elements, the possible orders it can have are 2 x 9, 3 x 6, 18 x 1, 1 x 18, 6 x 3, 9 x 2 and if matrix have 5 elements then order will be 1 x 5 or 5 x 1.
