Question

which of the following matrix multiplications would not be possible...optio A. a5×6 matrix with 6×3..B a4×3matrix with 3×3.. C 2×2 matrix with 3×3 D5×6matrix with 3×3

Answer 1

a matrix is multiplicable if the number of rows in one is equal to number of columns in the other or vice versa

so according to it c and d options are ur ans

Answer 2

Given,

The order of the matrices is given a5*6 with 6*3, a4*3 with 3*3, c2*2 with 3*3, and d5*6 with 3*3 matrices.

To find,

We have to find that which matrix multiplications would not be possible.

Solution,

The matrix multiplication is not possible in c2*2 with 3*3 and d5*6 with 3*3.

The matrix multiplication is possible when the number of columns in the first matrix is equal to the number of rows in the second matrix and vice versa.

In a5*6 with 6*3, a4*3 with 3*3 the columns in the first matrix are equal to the rows in the second matrix.

In the case of c2*2 with 3*3, and d5*6 with 3*3 the columns in the first matrix are not equal to the rows in the second matrix.

Hence, the matrix multiplication is not possible in c2*2 with 3*3 and d5*6 with 3*3.
