If a matrix has 5 elements, write all possible orders it can have.

Text Solution

Verified by Experts

A matrix of `mxxn` order has `m*n` elements.
Here, we are given elements in the matrix is `5`.
`:. m*n = 5`
Factors of `5` are `5` and `1`.
So, possible values of `m` and `n` are `5` and `1` or `1` and `5` respectively.
So, possible orders are `(5,1)` and `(1,5)`.
