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)] , show that a d j A=3A^T .

If A=[(-1,-2,-2 ),(2, 1,-2),( 2,-2 ,1)] , show that a d j\ A=3A^T .

Find the adjoint of the matrix A=[{:(-1,-2,-2),(2,1,-2),(2,-2,1):}] and hence show that A (adj A)= |A| I_

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

A=[{:(1,-1,2),(2,3,5),(-2,0,1):}] then find (adj A)
