To solve :Aparticular mathematical operation based on the given matrices
Answer to Problem 10CYU
The given operation is not possible.
Explanation of Solution
Given information:
The matrices A, B, C and D are given as,
The operation to be performed is -5B-2D
Calculation:
Here the individual matrices to be added are - 5B and - 2D . The matrix -5B can be calculated as,
Now, the matrix - 2Dcan be obtained as,
Finally, the sum of the matrices can be calculated as
It can be observed that, the order of the above matrices is not same. The first matrix is of the order 2×2 and the second matrix has the order 2×3. Hence, the addition for the matrices is not possible irrespective of the fact that the third column of the second matrix has all entries as zero.
