If possible find the sum of the matrics ...

If possible find the sum of the matrics A and B, where
`A=[{:( sqrt(3),1),(2,3):}]` and `B=[{:(x,y,z) ,(a,b,c):}]`

A

`2+a+b`

B

`sqrt(3)+x+y+z+a+b`

C

`sqrt(3)+x+y+z+a+b+2c`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
We have, `A=[{:(sqrt(3),1),(2,3):}]_(2xx2)"and" B=[{:(x,y,x),(a,b, 6):}]_(2xx3)`
Here A and B are of different orders, Also we know that the addition of two matrices A and B is possible only if order of both the matricles A and B should be same.
Hence , the sum of matrices A and B is not possible.
