Formula for pokemons level from its exp?

How do i calculate a pokemons level from the amount of exp it has?

Say we use the slow growth rate. At 1,250,000 exp a pokemon would be level 100. The formula for this is

EXP = (1.25 *(level ^3))

however how does the exp become its level? (i.e: reversing the equation so that it displays a pokemons level from its exp, rather than its exp from its level)

I currently have the below formula from just reversing the equation, however its not correct

LEVEL = floor(((exp ^(1/3)) /1.25))

There are actually multiple formulas, as there are different types of experience groups: Erratic, Fast, Medium Fast, Medium Slow, Slow, and Fluctuating. All the formulas assume n=# of experience points. Hopefully you guys know what piecewise functions are!

This is forpokemonlike Zangoose, Rampardos, Huntail, and Milotic.

Pokemonlike Clefairy and Chansey fall here.

This is the most common group, withpokemonlike Ferrothorn here.

Pokemonlike Shaymin and Mew are here.

Pokemonlike Houndoom or Rayquaza go here.

If you want to see what numbers correspond to what level, gohere.

Note that the stat formulas togainexperience vary between Gen I-IV and Gen V.
