Chapter 4: Q24. (page 172)

Find each product, if possible.
$[\begin{matrix} 7 & 3 \\ 0 & 2 \\ 5 & 5 \end{matrix}] \cdot [\begin{matrix} - 2 & 1 & 4 \\ 3 & - 5 & 2 \\ 4 & 3 & 1 \end{matrix}]$

Short Answer

Expert verified

The product for provided matrices is not possible.

Step by step solution

Step 1- Determine the dimensions of the provided matrices

The dimensions for first matrix are represented by $3 \times 2$ and for second matrix are represented by . $3 \times 3$

– Write the inner dimensions

The inner dimensions for both the provided matrices are represented by the numbers 2 and 3.

Step 3- Make the conclusion

As the inner dimensions of provided matrices are not the same which means that the product for the provided matrices is not defined.
