If `A` is a nilpotent matrix of index 2, then for any positive integer `n ,A(I+A)^n` is equal to (a) `A^(-1)` (b) `A` (c) `A^n` (d) `I_n`

If A is a square matrix such that |A| = 2 , then for any positive integer n, |A^(n)| is equal to

(-i)^(4n+3) , where n Is a positive integer.

If A is askew symmetric matrix and n is an odd positive integer, then A^(n) is

For a positive integer n , find the value of (1-i)^(n) (1 - 1/i)^(n)

For a positive integer n , find the value of ( 1-i)^n(1-1/i)^ndot

For a positive integer n , find the value of (1-i)^n(1-1/i)^ndot

If I_n is the identity matrix of order n, then rank of I_n is

If A is a skew-symmetric matrix and n is a positive even integer, then A^(n) is

If A is a skew-symmetric matrix and n is odd positive integer, then A^n is

If Aa n dB are square matrices of the same order and A is non-singular, then for a positive integer n ,(A^(-1)B A)^n is equal to A^(-n)B^n A^n b. A^n B^n A^(-n) c. A^(-1)B^n A^ d. n(A^(-1)B^A)^
