Mathematical SBI contest #5 Results and Solution of the Equation


The problem of the last contest was:

All solutions to this equation follow one general formula. This can be reached by setting the whole equation equal to a new variable z⁶:
x² = y³ = z⁶

x = z³
y = z²
If z is an integer, then x and y are also integer, so the general result is:
(z³, z²)

Sadly most people forgot that z can also be negative, but luckily that won't have a negative impact today.


How your chance of winning is calculated:

  • Every participant gets 1 point for entering the contest.
  • Every solution entered gets 1 additional point.
  • Multiple examples of a general solution count as one solution
  • If there is only one general solution, those who found its pattern(by mentioning a general formula or showing more then 3 examples) will get an additional point.
  • Your winning chance is "your points"/"total points"
