What is the element a_23 in matrix A
8 -4 -3
A=3 -9 -5
-8 8 8
-5
3
-4
8
The element a_23 in matrix A is -5.
To find the element a_23 in matrix A, we need to look at the second row and third column of matrix A.
The given matrix A is:
8 -4 -3
3 -9 -5
-8 8 8
Therefore, the element in the second row and third column of matrix A is -5.
To find the element a_23 in matrix A, we need to locate the element in the second row (row 2) and the third column (column 3) of the matrix.
Looking at matrix A, we can see that the second row consists of the numbers 3, -9, and -5. The third column consists of the numbers -3, -5, and 8.
To find the element in the second row and third column, we locate the intersection of the second row and third column, which corresponds to the element a_23.
In this case, the element a_23 is -5.
