Answer:
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]...
