Compute the entry (the number in the second row and second column) of the product matrix resulting from the following multiplication:
[1 2] [9 6]
[3 4] [5 7]

The entry on the second row and second column of the product matrix is .

Step-by-step explanation:

Let's define as A and B the given matrixes:

The product matrix C entry in the first row and first column or can be computer multiplying first row of A by first column of B (see example attached).

The product matrix C entry in the first row and second column or can be computer multiplying first row of A by second column of B.

The product matrix C entry in the second row and first column or can be computer multiplying second row of A by first column of B.

The product matrix C entry in the second row and second column or can be computer multiplying second row of A by second column of B.

Then, let's compute by doing the dot product between [3 4] and [6 7]...
