`If` `A=[[1,0,0],[0,1,0],[0,0,1]]` then value of `|A+A'|` is`

If A=[[1,0,0],[0,1,0],[a,b,-1]] , find A^2

If A=[[-1, 0 ,0], [0,-1, 0], [0, 0,-1]] , find A^2 .

If A=[[-1, 0, 0], [0,-1, 0], [0, 0,-1]] , find A^3 .

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

If A=[[0,i],[i,1]] and B=[[0, 1],[1, 0]] , find the value of |A|+|B| .

If A^(-1)=[[1,-1, 2],[0, 3,1],[ 0 ,0,-1/3]] , then |A|=-1 b. adj A=[[-1, 1 ,-2],[ 0,-3,-1],[ 0, 0, 1/3]] c. A=[[1, 1/3, 7 ],[0, 1/3, 1],[0 ,0,-3]] d. A =[[1,-1/3,-7],[ 0,-3, 0],[ 0, 0, 1]]

if [{:(1,2,a),(0,1,4),(0,0,1):}]^n=[{:(1,18,2007),(0,1,36),(0,0,1):}] then find the value of n

If A=[{:(1,0,0),(0,1,0),(a,b,-1):}] then A^(2) is equal to

If A=[{:(1,0,0),(0,1,0),(a,b,-1):}] then A^(2) is equal to

If A^(-1)=[{:(,1,-1,0),(,0,-2,1),(,0,0,-1):}] then
