To find: A + B.
Answer to Problem 108RE
A + B is not possible.
Explanation of Solution
Given information :
Finding A + B,
The above operation is not possible since matrices are of different order.
So, A + B is not possible.
To find: A − B.
Answer to Problem 108RE
A − B is not possible.
Explanation of Solution
Given information :
Finding A − B,
The above operation is not possible since matrices are of different order.
So, A − B is not possible.
To find: 2A.
Answer to Problem 108RE
Explanation of Solution
Given information :
Finding 2A,
So,
To find: A + 3B.
Answer to Problem 108RE
A + 3B is not possible.
Explanation of Solution
Given information :
Finding A + 3B,
So,
