Chapter 6.6, Problem 1BCYP

To determine

To find: the dimension of given matrix and the position of circled element.

Answer to Problem 1BCYP

The dimension of matrix is $2\text{ rows and 2 columns}$ . It is a $2\times 2$ matrix. The circled element is in the second row and second column.

Explanation of Solution

Given:

  $\left[\begin{array}{l}-3\text{ 6}\\ 4\text{ -8}\end{array}\right]$

Calculation:

The dimension of the matrix and the position of the circled element is calculated below

  $\left[\begin{array}{l}-3\text{ 6}\\ 4\text{ -8}\end{array}\right]$

The dimension of matrix is $2\text{ rows and 2 columns}$ .

The circled element is in the second row and second column.

Conclusion:

Therefore, the dimension of matrix is $2\text{ rows and 2 columns}$ . It is a $2\times 2$ matrix. The circled element is in the second row and second column.
