The answer is the first one, 41.

The value of a21 is 41

  • To take the product of two matrices, we will multiply the row of the first matrix and the column of the second matrix to get the resulting matrix;

  • From the given matrices, to get a21, you will multiply the second row of the first matrix with the first column of the second to have:

a21 = (7*5) + (2*3)

a21 = 35 + 6

a21 = 41

Hence the value of a21 is 41
