If A is a non singular square matrix; then `adj(adjA) = |A|^(n-2) A`

If A is a non - singular matrix then

If A is a non singular square matrix 3 then |adj(A^3)| equals (A) |A|^8 (B) |A|^6 (C) |A|^9 (D) |A|^12

Assertion: |AadjA|=-1 , Reason : If A is a non singular square matrix of order n then |adj A|=|A|^(n-1) (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.

If A is a non singular square matrix then |adj.A| is equal to (A) |A| (B) |A|^(n-2) (C) |A|^(n-1) (D) |A|^n

If A is an invertible square matrix; then adj A^T = (adjA)^T

If A is a singular matrix, then A (adj A) is a

If A is a 2xx2 non singular matrix, then adj(adj A) is equal to :

If A is a 2xx2 non singular matrix, then adj(adj A) is equal to :

If A is a non singular matrix of order 3 then |adj(adjA)| equals (A) |A|^4 (B) |A|^6 (C) |A|^3 (D) none of these

If A is a non-singular square matrix such that |A|=10 , find |A^(-1)|
