If `|[2x,-1],[4,2]|=|[3,0],[2,1]|` then `x` is

1.If |[2x,-1],[4,2]|=|[3,0],[2,1]| ,then value of x is (a) 3 (b) 2/3 (c) 3/2 (d) -1/4

If |[1,x,x^2] , [x,x^2,1] , [x^2,1,x]|=3 then find the value of |[x^3-1, 0, x-x^4] , [0,x-x^4, x^3-1] , [x-x^4, x^3-1, 0]|

Solve for x: /_\=|[2x,3,1],[4,6,x],[3x,1,1]| = 0

If [1, x, 2][[2,3,1],[0,4,2],[0,3,2]][[x],[1],[-1]]=0, then the value of x is

If [1,x,2][[2,3,1],[0,4,2],[0,3,2]][[x],[1],[-1]]=0 , then the value of x is

" 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 [[x, 4, 1]] [[2,-1,2] , [1,0,2] , [0,2,-4]] [[x], [4], [1]]=0 then find x

If x+2y=[[2,0,3],[1,-1,1]] and 2x-y=[[1,-4,-5],[0,2,-1]] then

Given A=[[1,-1, 0], [2, 3, 4], [0, 1, 2]], B= [[2,2,-4],[-4,2,-4],[2,-1,5]] find AB and use this to solve the system of equations: y+2x=7,x-y=3,2x+3y+4z=17

If x+2y=[[2,0,3],[1,-1,1]] and 2x-y=[[1,-4,-5],[0,2,-1]] ,then
