If `A` is a square matrix such that `A^2=A` , show that `(I+A)^3=7A+I` .

If A is square matrix such that A^(2)=A , then show that (I+A)^(3)=7A+I .

If A is a square matrix such that A^(2)=A, then (I-A)^(2)+A=

If A is a square matrix such that A A^T=I=A^TA , then A is

If A is a square matrix such that A^(2)=A, then (I+A)^(3)-7A is equal to (a) A (b) I-A(c)I(d)3A

If A is a square matrix such that A^(2)= I , then (A-I)^(3)+(A+I)^(3)-7A is equal to

If A is a square matrix such that A^(2)=I, then (A-I)^(3)+(A+I)^(3)-7A is equal to A(b)I-A(c)I+A(d)3A

If A is a square matrix such that A^(2)=A then write the value of 7A-(I+A)^(3), where I is the identity matrix.

Assertion (A) : If A is square matrix such that A ^(2) = A, then ( I + A)^(2) - 3 A = I Reason (R) : AI = IA = A

If A is a square matrix such that A^(2)=1 then (A-I)^(3)+(A+I)^(3)-7A is equal to
