" If "A=[[1,-1,2],[3,0,-2],[1,0,3]]" then prove that "A.(adj A)=|A|I." Also,find "A^(-1)

If A=[[1,-1,2],[3,0,-2],[1,0,3]] then prove that A*(adjA)=|A|I Also,find A^(-1)

If A = [[1,-1,2],[3,0,-2],[1,0,3]] prove A.adjA=|A|I Also,find A^ (− 1)

If A = [[1,3,3],[1,4,3],[1,3,4]] , then verify that A. adj A = |A|I. Also find A^-1 .

If A=[{:(,1,3,3),(,1,4,3),(,1,3,4):}] then verify that A adj A=|A| I. Also find A^(-1)

If A= [[2,1,0],[0,2,1],[1, 0,2]] then |adj A|=

If A=[[1,2,3],[1,3,4],[1,4,3]] ,verify that A(adj.A)=(adj.A)=|A|.I

If A = {:((1,-1,2),(3,0,-2),(1,0,3)):} , verify that A (adj A) = |A|* I .

If A=[[1,3,31,4,31,3,4]], then verify that Aquad adj,A,=|A|I .Also find A^(-1)

[" (1) Find the adjoint of "A" ,where "A=[[1,-1,0],[2,3,-2],[2,0,1]]],[" Also verify that "A*(adj A)=|A|I_(3)" ."]

If A = {:[(1,3,3),(1,4,3),(1,3,4) ]:} , then verify that A adj A = |A| I. Also find A^(-1)
