To find product of below matrices AB, if possible.
And also to state the dimension of result.
Answer to Problem 40E
The product of given matrices is:
And also the dimension of AB is:
Explanation of Solution
Given:
The matrices:
Concept Used:
If
Calculation:
In order to find product of below matrices AB
First check if this product is possible.
Note that here number of columns of A and number of rows of B are same (3). Thus this product is possible.
Now find this product
Note that the number of rows and number of columns in matrix AB 3 and 3 respectively.
Thus, product of given matrices is:
And also the dimension of AB is:
