If `AB=A` and `BA=B` then `B^2=`

If A and B are two square matrices of same order satisfying AB=A and BA=B, then B^2 is equal to A (B) B (C) A^2 (D) none of these

If A and B are two square matrices of same order satisfying AB=A and BA=B, then B^2 is equal to (A) A (B) B (C) A^2 (D) none of these

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 AB = A and BA = B then B'A'= A' and A'B' = B' and hence prove that A' and B' are idempotent.

If A and B are two matrices such that AB=A and BA=B, then B^(2) is equal to (a) B( b) A(c)1(d)0

If A and Bare square matrices of same order such that AB = A and BA = B, then AB^(2)+B^(2)= : a) AB b) A+B c) 2AB d) 2BA

If A and B are two matrices such that AB=B and BA=A , then A^2+B^2=

If A and B are two matrices such that AB=B and BA=A , then A^2+B^2=

If A and B are square matrices of the same order such that AB=A and BA=B ,then (A^(2)+B^(2))=?

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
