Question

If a matrix has 28 elements, what are the possible orders it can have. What if it has 13 elements??

Answer 1

Answer:

The possible order it can have :

1*28 , 2*14 , 4*7 , 7*4 , 28*1 , 14*2

Similarly the orders of 15 elements is 1*13 or 13*1 .

Answer 2

Answer:》》》》

If a matrix is of order m×n.So the elements of the matrix is m×n.

Hence we have to find all possible orders of a matrix with 28 elements.

Find all possible ordered pair of natural numbers whose product is 28.

All possible ordered pairs are

⇒ (1,28),(28,1),(14,2),(2,14),(4,7),(7,4)

Hence the possible orders are (1,28),(28,1),(14,2),(2,14),(4,7),(7,4).
