" Q3) 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 (A) null matrix (B) unit matrix (C) -A (D) A

If A[(1, 0, 0),(x, 1, 0),(x, x, 1)] and I=[(1, 0, 0),(0,1,0),(0,0,1)] , then A^(3)-3A^(2)+3A is equal to

If A=[(1,0,0),(0,1,0),(1,b,-10] then A^2 is equal is (A) unit matrix (B) null matrix (C) A (D) -A

If A=[(1,0,0),(0,1,0),(1,b,0] then A^2 is equal is (A) unit matrix (B) null matrix (C) A (D) -A

If A=[(0,1),(0,2)],B=[(1,2),(0,0)] , then AB is equal to

If A=[[0,1],[1,0]] , then A^2 is equal to: (a) [[0,1],[1,0]] (b) [[1,0],[0,1]] (c) [[1,0],[1,0]] (d) [[0,0],[1,1]]

If A=[[x,1],[1,0]] and A^2=I , then A^(-1) is equal to: a) [[0,1],[1,0]] b) [[1,0],[0,1]] c) [[1,1],[1,1]] d) [[0,0],[0,0]]
