Chapter 9, Problem 1RE

To determine

The order of the given matrix.

Answer to Problem 1RE

Order of the given matrix is$1\times 4$.

Explanation of Solution

Given information:

Given matrix is $\left[\begin{array}{cccc}-1& 2& 3& 4\end{array}\right]$

Concept used:

As we know the order of a matrix is given as $m\times n$where $m$is the number of rows in the matrix and $n$is the number of column in the matrix.

Calculation:

As we can observe the number of rows and number of columns in the given matrix is $\text{1 and 4}$respectively. Hence, the order of the given matrix is $1\times 4$.

Conclusion:

Hence, order of the given matrix is$1\times 4$.
