If A dn B be `3xx3` matrices the AB=0 implies (A) `A=0 or B=0` (B) `A=0 and B=0` (C) `|A|=0 or |B|=0` (D) `|A|=0 and |B|=0`

A and B be 3xx3 martrices. Then AB=0 implies

If A and B are any 2xx2 matrices then det(A+B)=0 implies (A) detA+detB=0 (B) detA=0or detB=0 (C) AB=0rarr|A|=0 and |B|=0 (D) AB=0rarrA=0 or B=0

A and B be 3xx3 matrices such that AB+A=0 , then

A and B be 3xx3 matrices such that AB+A=0 , then

A and B be 3xx3 matrices such that AB+A+B=0 , then

A and B be 3xx3 matrices such that AB+A+B=0 , then

If A and B are any 2xx2 matrices , then det (A+B) = 0 implies :

6.If A and B are matrices with AB=0 and BA=0 ,then a) A=0 or B=0 b) Either A=0 or B=0 c) A=0 and B=O d) None of these.

If A and B are square matrices of order 3 then (A) AB=0rarr|A|=0 or |B|=0 (B) AB=0rarr|A|=0 and |B|=0 (C) Adj(AB)=Adj A Adj B (D) (A+B)^-1=A^-1+B^-1
