Let A=[{:(1,-2,1),(-2,3,1),(1,1,5):}] . Verify that ltbtgt (i) [adjA]^(-1)=adj (A^(-1)) (ii) (A^(-1)^(-1)=A

Let A = [[1,-2,1],[-2,3,1],[1,1,5]] Verify that [adj A]^-1 = adj (A^-1)

Let A=[{:(1,-2,1),(-2,3,1),(1,1,5):}] Verify that [adjA]^(-1)=adj(A^(-1))

If A=[[2,5,33,1,21,2,-1]] be a square matrix,find Adj.A and A^(-1)

A=[{:(2,-3),(4,6):}] verify (adjA)^(-1)=(adjA^(-1))

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

If A = [(a,b),(c,d)] show that, (i) adj (adj.A) = A (ii). (A^(-1))^(-1) = A .

If A=[[1,2,1],[1,1,2],[2,2,1]] verify A(adj A)=(adj A)A=|A|I_(3) .

If A = [[1,-1,2],[3,0,-2],[1,0,3]] verify that A(adjA) = (adjA)A = abs(A)I ,
