If `A=[[x,1]][[1,0],[-2,0]]`=0` , then x is equals to

If [[x,1]][[1,0],[2,0]]=0 ,then x equals (A) 0 (B) -2 (C) -1 (D) 2

If [(x,1)][(1,0),(-2,0)] = 0, then x equals

If X + [ [ 2 , 1 ] , [ 6 , 1 ] ] = [ [ 1 , 1 ] , [ 0 , 1 ] ] , then X is equal to ( 1 ) [ [ 0 , 1 ] , [ 0 , 6 ] ] ( 2 ) [ [ 0 , -1 ] , [ 0 , - 6 ] ] ( 3 ) [ [ -1 , 0 ] , [ - 6 , 0 ] ] ( 4 ) [ [ 1 , 0 ] , [ 6 , 0 ] ]

" If the trace of the matrix: "A=[[-1,0,2,5],[3,x^(2)-2,4,1],[-1,-2,x-3,1],[2,0,4,x^(2)-6]]" is "0" then "x" is equal to "

If [(1,4),(2,0)] = [(x,y^(2)),(z,0)] y lt 0 then x-y+z is equal to

If A=[(2x,0),(x,x)] and A^(-1)=[(1,0),(-1,2)] then x equals to

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=[(2,1),(0,x)] and A^(-1)=[(1/2,1/6),(0,1/x)] , then the value of x is equal to

If x=10.0pm0.1 and y=10.0pm0.1 , then 2x-2y is equal to
