Quizplus · Accepted Answer

The product of two matrices can be found by multiplying the corresponding entries and adding them up. For example, the entry in the first row and first column of the product matrix is found by multiplying the first row of the first matrix with the first column of the second matrix: (2*3)+(1*1)=7. Similarly, the entry in the first row and second column of the product matrix is found by multiplying the first row of the first matrix with the second column of the second matrix: (2*2)+(1*0)=4. Continuing in this manner, we get the product matrix as:
| 7  4 |
| 5  2 |
Therefore, the correct choice is C.
