If nth-order square matrix A is a orthogonal, then `|"adj (adj A)"|` is

If A is a orthogonal matrix, then

If A is order 3 square matrix such that |A|=2 , then |"adj (adj (adj A))"| is

If A is order 2 square matrix such that |A|=2, then |(adj(adj(adjA)))| is 512 b. 256 c. 64 d. none of these

If A is an orthogonal matrix, then |A| is

Let A be an nth-order square matrix and B be its adjoint, then |A B+K I_n| is (where K is a scalar quantity) (|A|+K)^(n-2) b. (|A|+)K^n c. (|A|+K)^(n-1) d. none of these

If A is a square matrix of order n, then |adj A|=

If square matrix a is orthogonal, then prove that its inverse is also orthogonal.

If A is a square matrix of order 3 such that |A|=5 , then |Adj(4A)|=

If A and B are square matrix of same order then (A-B)^(T) is:
