TypeSolve power equations
DifficultyEasy -1.2 This is a straightforward rearrangement requiring cube root extraction from a formula. It's simpler than average A-level work as it only tests basic algebraic manipulation of indices with no problem-solving element—purely mechanical application of inverse operations.
