If B is an idempotent matrix, and `A=I-B`, then

A square matrix A is used to be an idempotent matrix if A^(2) = A . If A is an idempotent matrix and B = I -A, then-

If B an idempotent matrix and A=I-B then AB =

If A is an idempotent matrix and I is an identify matrix of the Same order, then the value of n, such that (A+I)^n =I+127A is

If A is an idempotent matrix and I is an identify matrix of the Same order, then the value of n, such that (A+I)^n =I+127A is

If A is an idempotent matrix and I is an identify matrix of the Same order,then the value of n, such that (A+I)^(n)=I+127A is

If A is an idempotent matrix and I is an identify matrix of the Same order, then the value of n, such that (A+I)^n =I+127A is

If A!=I is an idempotent matrix, then A is a

If Z is an idempotent matrix, then (I+Z)^(n)

If Z is an idempotent matrix, then (I+Z)^(n)

If A is an idempotent matrix, then show that B=l-A is also idempotent and AB=BA=0
