1. Simplify the complex fraction  [(x-4)(x^2-4)]/[(x^2-16/(x-2)]


  [(1/x) divided by (x-8)]

 1/[(x+2)(x+4)]

  (x-2)/[(x^2-4)(x-4)]


2. Simplify the complex fraction  [2/x+2/y] divided by [2/x - 2/y]

  (y+x)/(y-x)

  (2y+2x)/(2y-2x)

  -1


3. Simplify the complex fraction  [(10x-10y)/(x^3-y^3)] divided by [(5x)/(x^2+xy+y^2)]

  (10x-10y)/(5x(x-y))

  5/10x

   2/x
