If `A=[[1,0,0] , [0,1,0] , [a,b,-1]]` then

If A=[[0,0,1] , [0,1,0] , [1,0,0]] then A^6=

If A=[[1,0,0],[0,1,0],[a,b,-1]] and A=A^(-1) then a+b=?

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

If A=[[1, 0, 0], [a, 1, 0], [b, c, 1]] , then A^(-1)=

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

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

Given A=[[1,0,0],[0,-1,0],[0,0,-1]] and B=[[2,x,x],[x,4,5],[x,6,7]] : determine the value of x , if there be any , for which the property AB=BA may hold.

If A=[[1,0],[0,1]],B=[[1,0],[0,-1]] and C=[[0,1],[1,0]] then show that A^(2)=B^(2)=C^(2)
