Calculation steps
- 1Find nearest perfect cubes: 4³ = 64 ≤ 100 ≤ 125 = 5³
- 2So ∛100 is between 4 and 5
- 3Linear interpolation: fraction = (100 − 64) / (125 − 64) = 0.590
- 4More precisely, ∛100 = 4.6415888

💡 Trick: a cube ends in the same digit as its root (1³=1, 2³=8 ends 8 ↔ 2, 3³=27 ends 7 ↔ 3, 8³=512 ends 2 ↔ 8...). For two-digit cube roots, split the number at the thousands: the left part gives the tens digit (nearest cube below), the last digit gives the units digit.
