If A and B are two square matrices of or...

If A and B are two square matrices of order `3xx3`, then whilch of the following is true?

A

`AB=OimpliesA=O` or `B=O`

B

det`(2AB)=8` det(A) det(B)

C

`A^(2)-B^(2)=(A+B)(A-B)`

D

det (A+B)=` det` (A) `+` det(B)

Text Solution

Verified by Experts

The correct Answer is:
B
`det(2AB)=2^(3)det(A)det(B)=8det(A)det(B)`
