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`

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

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

If A and B are square matrices of the same order, then AB = 0 implies

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 square matrices of order 2, then det(A+B)=0 is possible only when (a) det(A)=0 or det(B)=0 (b) det(A)+det(B)=0 (c) det(A)=0 and det(B)=0 (d) A+B=O

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
