Chapter 8, Problem 1RE

To determine

Find the order of the given matrix.

Answer to Problem 1RE

The order of the matrix is $3\times 1$ .

Explanation of Solution

Given information:

The given matrix is

  $\left[\begin{array}{c}-4\\ 0\\ 5\end{array}\right]$

Calculation:

A matrix having $m$ rows and $n$ columns is said to be of order $m\times n$ .

If $m=n$ , then the matrix is square of order $m\times m$ or $n\times n$ .

In the given matrix $m=3$ and $n=1$ .

Hence the order of the matrix is $3\times 1$ .
