(If x proportional to y, then prove that x^3+y^3 proportional to x^2y-xy^2)
Variation
Prove that
Constant

  1. If `x prop y` then prove that `x^3+y^3 prop x^2y-xy^2`
  2. If `x prop y` then prove that `x^2+y^2+xy prop x^2-y^2`
  3. If `x prop y, y prop z` then prove that `x^3+y^3+z^3 prop xyz`
  4. If `y prop z, x prop y` then prove that `x^3+y^3+z^3 prop xyz`
  5. If `5x-7y prop 6x+3y` then prove that `x prop y`
  6. If `5x+2y prop 3x-7y` then prove that `x prop y`
  7. If `9x-3y prop 4x+5y` then prove that `x prop y`
  8. If `2x^2-3y^2 prop 4x^2+5y^2` then prove that `x prop y`
  9. If `4x^3+5y^3 prop 2x^3-9y^3` then prove that `x prop y`
  10. If `x^2+9y^2 prop xy` then prove that `x prop y`
  11. If `4x^2+9y^2 prop xy` then prove that `x^2+y^2 prop xy`
(Note: For proportional '`prop`' sign, we use '@' sign for input)
