Question

Use the following matrices to perform the indicated operation, when possible. (If not possible, enter IMPOSSIBLE into any cell of the matrix.) C = 9 3 1 2 D = 4 8 7 5 Find CD.

Answer 1

Answer:

IMPOSSIBLE

Step-by-step explanation:

[tex] c = \begin{matrix}  9  3  1  2 \end{matrix} [tex] i.e. 1 Row and 4 Columns

[tex] D = \begin{matrix}  4  8  7  5 \end{matrix} [tex] i.e.  1 Row and 4 Columns

The first rule of matrix is that the number of columns in the first fix matrix should equal the number of rows in the second matrix;

In this instance the number of columns in the first matrix does not equal the number of rows in the second matrix, hence the multiplication is impossible.
