Determine the value of $d_{23}$ in the given $2 \times 3$ matrix $D$ . If $d_{23}$ is not present, state "None".

STEP 1

Assumptions1. The given matrix D is ax3 matrix, meaning it has rows and3 columns. . The element $d_{23}$ refers to the element in thend row and3rd column of the matrix.

STEP 2

We need to find the value of $d_{23}$ , which is the element at the2nd row andrd column of the matrix D.The matrix D is given as $=\left[\begin{array}{ccc} 4 &13 & -4 \\ 7 & -7 &1\end{array}\right]$

STEP 3

We can see that the element at the2nd row and3rd column of the matrix D is1.So, $d_{23} =1$ .
The value of $d_{23}$ is1.
