In this question, we know that for multiplication, for multiplication of two matrix, two matrix, the number of columns, the number of columns in first matrix, in first matrix must be equal to, must be equal to the number of, equal to the number of rows in the, in the second matrix.

Now, in this case, we are given with a and, a and b are 8 by 6 matrix and, and c is 7 by 8 matrix.
01:09
Now, if we consider, if we consider a, b, if we consider b into a, so b is, b is 8 by 6 matrix and a is also 8 by 6 matrix and this is, this is row 1, column 1, this is row 2, column 2.
01:37
Now, the column of first matrix which is 6 is not equal to row second matrix which is a.
01:47
So, therefore, therefore b, a is not possible, b, a is not possible...
