Answer to Problem 26PPE
Explanation of Solution
Given:
The given matrix is
Concept used:
Scalar multiplication of the matrix: scalar multiplication refers to the product of a real number and a matrix. In scalar multiplication, each element in the matrix is multiplied by the given scalar.
The sum or differences of the any matrix is possible, when the number of elements of both matrices are same. i.e. number of columns are same and number of rows are same.
Calculation:
The given matrix is
Here number of elements in both matrices are same.
Therefore, first apply the scaler multiplication and then subtract the matrix. Now,
Hence, the simplified form of the given matrix is
