If a matrix has 24 elements, what are the possible order itcan have? What, if it has 13 elements? |

Answer» We know that, if a matrix is of order m x n, it has mn elements, where m and n are natural numbers.We have, m x n = 28⇒ (m, n)= {(1, 28), (2, 14), (4, 7), (7, 4), (14, 2), (28, 1 )}So, the possible orders are I x 28, 2 x 14, 4 x 7, 7 x 4, 14 x 2, 28 x 1.Also, if it has 13 elements,then m x n = 13⇒ (m, n)= ((1, 13), (13, l)}Hence, the possible orders are 1 x 13, 13 x 1. |
