Answer to Problem 21PPS
Explanation of Solution
Given information:
Calculation:
In order for matrix multiplication to be defined, the number of Columns in the first matrix must be equal to number of rows of second matrix.
Let Matrix A be in form
Matrix B be in the form
Then the product matrix will be in the form
Here
As the number of Columns of first matrix is equal to number of rows of second matrix.
So, the Product
And the product
Therefore,
