If A and B are square matrices of the same order such that AB = A and BA = B, then……

If A and B arę square matrices of same order such that AB = A and BA = B, then

If A and B are two square matrices of the same order such that AB=B and BA=A , then A^(2)+B^(2) is always equal to

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 square matrices of the same order such that AB = A, BA = B and if a matrix A is called idempotent if A^(2)=A , then

If A and B are non-zero square matrices of same order such that AB=A and BA=B then prove that A^(2)=A and B^(2)=B

If A and B are two square matrices of the same order, then AB=BA .

if A and B are square matrices of same order such that A = and B = B, where A denotes the conjugate transpose of A, then (AB-BA)* is equal to

if A and B are square matrices of same order such that A*=A and B* = B, where A* denotes the conjugate transpose of A, then (AB-BA)* is equal to

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