Chapter 4: Q8. (page 171)

Find each product, if possible.
$[\begin{matrix} 5 & - 2 & - 1 \\ 8 & 0 & 3 \end{matrix}] \cdot [\begin{matrix} - 4 & 2 \\ 1 & 0 \end{matrix}]$

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

– Write the inner dimensions

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

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.
