Q-60quad " If "A^(3)=O," then "I+A+A^(2)" equals (where I is the unit matrix of order same that of square matrix 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 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 I is unit matrix of order n, then 3I will be

For a matrix A, if A^(2)=A and B=I-A then AB+BA +I-(I-A)^(2) is equal to (where, I is the identity matrix of the same order of matrix A)

For a matrix A, if A^(2)=A and B=I-A then AB+BA +I-(I-A)^(2) is equal to (where, I is the identity matrix of the same order of matrix A)

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

If I is a unit matrix of order 10, then the determinant of I is equal to

If I is a unit matrix of order 10, then the determinant of I is equal to

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