If `A` is a skew symmetric matrix, then `B=(I-A)(I+A)^(-1)` is (where `I` is an identity matrix of same order as 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 is a skew-symmetric matrix of order 3, then |A|=

If A is a skew-symmetric matrix of order 3 then A^(3) is

If A is an idempotent matrix satisfying (I-0.4A)^(-1)=I-alphaA where I is the unit matrix of the same order as that of A then the value of alpha is

If A is skew-symmetric matrix then A^(2) is a symmetric matrix.

If A is a skew-symmetric matrix of odd order n, then |A|=0

If A is a skew-symmetric matrix of order 3 ,then the matrix A^(4) is

If A is skew-symmetric and B=(I-A)^(-1)(I+A), then B is
