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

Explanation

To solve the problem, we need to determine the possible orders of a matrix based on the number of elements it contains. The order of a matrix is defined by the number of rows and columns it has, and the total number of elements in a matrix is given by the product of its rows and columns.

### Step-by-Step Solution:

1. **Understanding the Problem**:
We need to find the possible orders of a matrix that has a specific number of elements. The order of a matrix is expressed as \( m \times n \), where \( m \) is the number of rows and \( n \) is the number of columns.

2. **Finding Possible Orders for 18 Elements**:
