If `A=[(5,0,0),(0,6,0),(0,0,7)]` then show that `A^(-1) = [(1/5,0,0),(0,1/6,0),(0,0,1/7)]`

If A = [{:( 0,0,0),( 1,0,0),(0,1,0):}] ,then

If A=[[0,0,1],[0,1,0],[1,0,0]] , show that A^(-1)=A

If A=[(1,-1,0),(1,0,0),(0,0,-1)] , then A^(-1) is

If A={:[(0,1,0),(1,0,0),(0,0,1)]:}," then "A^(-1)=

If A=[(1,-5,0),(0,7,0),(11,1,9)] then trace of matrix A is

If A=[(1,0),(0,3)] and B=[(2,0),(0,1)] then show AB =BA =[(2,0),(0,3)]

If A=[[1,0,0],[0,5,0],[0,0,2]] then | adj "A|=

The inverse of the matrix [(0,0,1),(0,1,0),(1,0,0)] is (A) [(0,0,1),(0,1,0),(1,0,0)] (B) [(0,0,-1),(0,-1,0),(-1,0,0)] (C) [(1,0,0),(0,1,0),(0,0,1)] (D) [(1/2,0,0),(0,1/2,0),(0,0,1/2)]
