  hmm.. in that first; couldn't it be all anwsers except E ?

  v = square root

  18v18 = rvt
  rvt = 76.36753

  1. r & t = positive
  2. r>t

  r*t = 18
  r*t = 36
  r*t = 108
  r*t = 162
  r*t = 324

  ----------------

  18^2 * 18 = r^2 * t
  r^2 * t = 5832

  if r*t = 18 then
  t = 18/r

  r^2 * 18/r = 5832
  r * 18 = 5832
  r = 5832/18 = 324

  t = 18/324 = 0.555~
  324v0.555~ = 76.36753 = 18v18

  if r*t = 36 then
  t = 36/r

  r^2 * 36/r = 5832
  r * 36 = 5832
  r = 5832/36 = 162

  t = 36/162 = 0.222~
  162v0.222~ = 76.36753 = 18v18

  if r*t = 108 then
  t = 108/r

  r^2 * 108/r = 5832
  r * 108 = 5832
  r = 5832/108 = 54

  t = 108/54 = 2
  54v2 = 76.36753 = 18v18

  if r*t = 162 then
  t = 162/r

  r^2 * 162/r = 5832
  r * 162 = 5832
  r = 5832 / 162 = 36

  t = 162/36 = 4.5
  36v4.5 = 18v18

  if r*t = 324 then
  t = 324/r

  r^2 * 324/r = 5832
  r * 324 = 5832
  r = 5832 / 324 = 18

  t = 324/18 = 18
  r !> t
