To determine

To find: The product of $C\times B$ .

Answer to Problem 9CT

The matrix cannot be multiply.

Explanation of Solution

Given information:

The given matrix,

Calculation:

Calculate the matrix,

If we multiply 2 matrices, the number of columns of the first matrix should be equal to the number rows of the second matrix.

We see that matrix $A$ and $3\times 2$ matrices. The number of columns in matrix $A$ is 2 and the number of rows in matrix $C$ is 3.

Therefore, the matrices cannot be multiplied.
