If `A=[{:(,1,2),(,2,1):}]` then adj A=

If A=|{:(,2,-3),(,-4,1):}| then adj (3A^(2)+12A) is equal to

If A=[{:(11,7),(-13,17):}] then adj(adj A) is

If A=|{:(,5a,-b),(,3,2):}| and A adj A=A A^(T) , then 5a+b is equal to

If A=[(1,2,0),(-1,1,2),(2,-1,1)] then det (Adj(AdjA))= (A) 13 (B) 13^2 (C) 13^4 (D) none of these

If A=[(3,4,3),(2,5,7),(1,2,3)] then |Adj(Adj A)|=

If {:A=[(0,1,-1),(2,1,3),(3,2,1)]:} then (A(adj A)A^(-1))A=

If [{:( 1,2,3),(1,3,5),(1,5,12):}] then adj (adj A) is

Let M=[{:(0,1,a),(1,2,3),(3,b,1):}] and adj M =[{:(-1,,1,,-1),(8,,-6,,2),(-5,,3,,-1):}] where a and b are real numbers. Which of the following options is/are correct ?

If A=[(1,2,-1),(-1,1,2),(2,-1,1)] , then det (adj (adjA)) is

Statement -1 : if {:A=[(3,-3,4),(2,-3,4),(0,-1,1)]:} , then adj(adj A)=A Statement -2 If A is a square matrix of order n, then adj(adj A)=absA^(n-2)A
