If A O, then I+ A A2 (where I is the unit matrix of order same as that of square matrix A) is equ (A) I -A (B) (I-A) 1 dp) none of these (C) (I+A)

If AO, then I+AA2 (where I is the unit matrix of order same as that of square matrix A) is equ (A) I-A(B)(I-A)1dp ) none of these (C)(I+A)

If A^3 =O, then I+ A + A^2 = (where I is the unit matrix of order same as that of square matrix A) is equals (A) I -A (B) (I-A)^-1 (C) (I+A) (D) none of these

If I is unit matrix of order n, then 3I will be

If A is skew symmetric matrix, then I - A is (where I is identity matrix of the order equal to that of A)

If A is skew symmetric matrix, then I - A is (where I is identity matrix of the order equal to that of A)

If A = [[4,5],[5,6]] , show that A^2 = 10A + I where I is the unit matrix of order 2.

If A = [[2,2],[4,3]] show that A A^(-1) = I_2 where I_2 is the unit matrix of order 2.

If A is a square matrix and I is the unit matrix of the same order as A, then A.I =
