If A and B are matrices such that A + B and AB are defined, then.
It is not necessary that A and B are of the same size.
A and B are square matrices of the same order
No. of columns in A = no. of rows in B
None of these
A square matrix A is singular if _______.
| A |≠ 0
| A | = 0
| A | = 1
A | ≠1
If the matrix AB is zero, then _________.
A = 0 or B = 0
A = 0 and B = 0
It is not necessary that either A = 0 or B should be 0
All the above statements are wrong
Then 3 A - 4 B =
