If `A=[(-1,-2,-2),(2,1,-2),(2,-2,1)],` then `A^(T)`

IF A=[{:(-1,-2,-2),(2,1,-2),(2,-2,1):}] then show that adj A=3A^T . Also find A^-1 .

IF A=[{:(-1,-2,-2),(2,1,-2),(2,-2,1):}] then show that adjA=3A^T Also find A^-1

If A=[[-1,-2,-2],[2,1,-2],[2,-2,1]] then show that the adjoint of A is 3A^(T) .Find A^(-1)

If A=(1)/(3){:[(-1,2,-2),(-2,1,2),(2,2,1)] show that "AA"^(T)=I .

If A=[[-1,-2,-2],[2,1,-2],[2,-2,1]], show that 3adjA=A^T.

If A=1/3({:(-1,2,-2),(-2,1,2),(2,2,1):}) , show that "AA"^(T)=I_(3) .

Let A=[[-1, -2 , -2],[ 2, 1, -2], [2, -2, 1]] If adj. A=k A^T theri the value of 'K' is

If A= [(2,1,2),(1,2,0),(2,1,-1)] ,B= [(1,1,0),(2,2,1),(1,0,-1)] Verify the following (iI) (A-B)^(T)=A^(T)-B^(T)
