Find the x if
`| [ x , 2 ] , [ 8 , 4 ] |` = `| [ 1 , 1] , [ 2 , 2 ] |`

If |[x,2],[8,4]|=|[1,1],[2,2]| then value of x

if |[x,2],[8,4]|=|[1,1],[2,2]| then value of x is

The factor of x^8 + x^4 +1 are (A) (x^4 + 1 - x^2), (x^2 +1 +x), (x^2 + 1 - x ) (B) x^4 + 1 -x^2 , (x^2 - 1 + x), (x^2 +1 + x) (C ) (x^4 - 1 + x^2, (x^2 - 1 + x), (x^2 + 1 + x) (D) (x^4 -1 + x^2), (x^2 + 1 - x), (x^2 + 1 +x)

Find the value of x if 2^(2x-1)=8^(x-3)

Find X and Y if, X+2Y = [[4,5],[3,8]] and 2X-Y = [[5,-2],[-1,1]]

If A=[[1,2],[3,4]] , B=[[3,8],[7,2]] and 2X+A=B then find X
