If `|[x,1],[1,x]|=|[2,0],[8,4]|`then value of `x`is :

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]|

If | (2x, -9), (-2, x) | = |(-4,8) , (1, -2)| , then value of x is

If A=[(2x,0),(x,x)] and A^(-1)=[(1,0),(-1,2)] , then the value of x is

If |(x,2,3),(2,3,x),(3,x,2)|=|(1,x,4),(x,4,1),(4,1,x)|=|(0,5,x),(5,x,0),(x,0,5)|=0, then the value of x equals (x in R):

If f(x) = {{:((sqrt(4+ax)-sqrt(4-ax))/x,-1 le x lt 0),((3x+2)/(x-8), 0 le x le 1):} continuous in [-1,1] , then the value of a is

If (2x4)(x-8)=0 , find the positive value of x
