`" If "AB=A,BA=B" then "A^(2)+B^(2)=[[" (A) ",A+B],[" (B) ",A-B],[" (C) ",AB],[" (D) ",O]]`

If AB=A and BA=B then B^(2)=

If AB = A and BA = B, then

If AB=A and BA=B, then show that A^(2)=A,B^(2)=B

if AB = A and BA = B, then

If AB= Aand BA=B, then a.A^(2)B=A^(2) b.B^(2)A=B^(2) c.ABA=A d.BAB=B

If A and B are two matrices such that AB=B and BA=A then A^2+B^2= (A) 2AB (B) 2BA (C) A+B (D) AB

If A and B are square matices of the same order such that A^2=A,B^2=B,AB=BA=0 then (A) AB^2=0 (B) (A+B)^2=A+B (C) (A-B)^2=A+B (D) none of these

If A and B are square matrices of the same order then (A+B)^2=A^2+2AB+B^2 implies (A) AB=0 (B) AB+BA=0 (C) AB=BA (D) none of these

If A=[(1,0,),(2,0)] and B=[(0,0),(1,12)] then= (A) AB=0, BA=0 (B) AB=0,BA!=0 (C) AB!=0,BA=0 (D) AB!=0,BA!=)
