Answer to Problem 17E
The value of
Explanation of Solution
Given:
The matrices
Concept used:
Operations like addition and subtraction of matrices are only possible when they are of same dimension.
Dimension of matrix with a rows and b columns is given by
If a matrix is multiplied by a scalar then each element of the matrix is multiplied by the same scalar.
Calculation:
Add the matrix A and Bas follows:
Thus, the value of
