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

If A=[[-2,3,8],[1,5,5],[0,2,4]], then trace of matrix A is

If A=[{:(3,-3,4),(2,-3,4),(0,-1,1):}] , then the trace of the matrix Adj(AdjA) is

If A=[{:(3,-3,4),(2,-3,4),(0,-1,1):}] , then the trace of the matrix Adj(AdjA) is

If A=[{:(3,-3,4),(2,-3,4),(0,-1,1):}] , then the trace of the matrix Adj(AdjA) is

If A=[{:(3,-3,4),(2,-3,4),(0,-1,1):}] , then the trace of the matrix Adj(AdjA) is

If A=[[1,3,2],[-1,2,0],[0,-1,1]] , then find a matrix X such that A^(2)-2A-X=0

If [(2,1),(7,4)]A[(-3,2),(5,-3)]=[(1,0),(0,1)] then matrix A equals

if [{:(3,2),(7,5):}]A{:[(-1,1),(-2,1):}]={:[(2,-1),(0,4):}] then trace of A is equal to
