Step-by-step explanation:
- The product of two matrices
and
equals a matrix
, where the first element of the subscript represents the amount of files of the matrix and the second element represents the amount of columns of the matrix. - Then, in this case
, therefore, its product will result a matrix
. - Because C matrix is going to have an only file and three columns, we now have to find the values of the elements in each column, based on the elements of A and B.
- Commonly, to obtain the values of the resulting matrix, we just have to multiply each file of the first matrix by each column of the second matrix and sum, as follows:



- Finally, C matrix is
