What leans on this
Chemistry that uses this algebra — the answer to why you are learning it.
Solving x³ = Ksp/4 for x is inverting a cubic power function — exactly the radical-function-as-inverse idea, since molar solubility is only recoverable by undoing the cube that the AB2 stoichiometry built into the Ksp expression.
