Concept explainers
To find: The product of two given matrices.
Answer to Problem 38E
The required product of the given matrices is
Explanation of Solution
Given: The two matrices are
Concept Used: Matrix multiplication is possible if and only if the number of columns in the first matrix is equal to the number of rows in the second matrix. Thus, two matrices
Calculations: The given matrices are
Since number of columns in A is equal to the number of rows in B , hence AB exists which will be a matrix of order
Thus the required product is-
Thus, the required product is
