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 = [[x,1,-x],[0,1,-1],[x,0,7]] and det (A) = |(3,0,1),(2,-1,0),(0,6,7)| , then the value of x is a)-3 b)3 c)2 d)-8

If A=[{:(,2,x),(,0,1):}] and B=[{:(,4,36),(,0,1):}] , find the value of x, given that A^2=B

IF " "[x,4,-1][[2,1,-1],[1,0,0],[2,2,4]][x,4,-1]^(TT) -0" then value of x:

If A=[[1/3,2],[0,2x-3]] , B=[[3,6],[0,-1]] and AB=I ,then x=

If [(x-1,2,5-y),(0,z-1,7),(1,0,a-5)]=[(1,2,3),(0,4,7),(1,0,0)] then find the values of x,y,z and a.

If A=[[2,5,6] , [0,1,2]], B =[[6,1] , [0,4] , [5,7]] then verify that (AB)'=B'A'

If A={:[(1,2,x),(0,1,0),(0,0,1)]:}, B={:[(1,-2,y),(0,1,0),(0,0,1)]:} and AB=I_(3) , then find the value of x + y + 1.

If A= ((1,0,0),(2,3,4),(5,-6,x)) and "det=45" then the value of "x" is

Let A=[[2,0,7] , [0,1,0], [1,-2,1]] and B=[[-x,14x,7x] , [0,1,0] , [x,-4x,-2x]] are two matrices such that AB=(AB)^(-1) and AB!=I then Tr((AB)+(AB)^2+(AB)^3+(AB)^4+(AB)^5+(AB)^6)=
