" 4.If "A=[[-1,-2,-2],[2,1,-2],[2,-2,1]]" ,then show that the adjoint of "A" is "3A" '.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,-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

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_

Find the adjoint of the matrix A = [(-1,-2,-2),(2,1,-2),(2,-2,1)] and hence show that A (AdjA) = |A | I_3

Find the adjoint of the matrix A=[(-1,-2,-2), (2, 1,-2) ,(2,-2, 1)] and hence show that A(a d j\ A)=|A|\ I_3 .

Find the adjoint of the matrix A=[(-1,-2,-2), (2 ,1,-2), (2,-2, 1)] and hence show that A(a d j\ A)=|A|\ I_3 .

Find the adjoint of the matrix A=[(-1,-2,-2), (2 ,1,-2), (2,-2, 1)] and hence show that A(a d j\ A)=|A|\ I_3 .
