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

If AB=A and BA=B then 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)=

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

Let A and B be square matrices of same order satisfying AB =A and BA =B, then A^(2) B^(2) equals (O being zero matrices of the same order as B)

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

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) is equal to
