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

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

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

If AB=A,BA=B then A^(2)+B^(2)=

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

For square matrices A and B , AB=A and BA =B, then prove that A^(2)=AandB^(2)=B .

If A, B are two square matrices such that AB = A and BA = B, then prove that B^(2) = B

If AB = A and BA = B, then which of the following is not true a)A is idempotent b)B is idempotent c) A^(T) is idempotent d)None of these

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

If AB=A and BA=B, then which of the following is/are true? A is idempotent b.B is is idempotent c.A^(T) is idempotent d.none of these
