What is the cube root of 55?
Answer
∛55 ≈
3.803
Real cube root: the only number whose cube is 55.
≈ — rounded to 4 decimal places. 55 is not the cube of a rational number, so ∛55 is irrational: its decimal expansion never ends and never repeats.
- Prime factors
- 55 = 5 × 11
- Take out of the root
- No prime appears three times, so ∛55 is already in simplest form.
- Between cubes
- 3³ = 27 < 55 < 64 = 4³, so 3 < ∛55 < 4 and ∛55 ≈ 3.803

FAQ
What is the cube root of 55?
∛55 ≈ 3.803
Can ∛55 be simplified?
No: no prime appears three times in 55, so its only cube factor is 1 and ∛55 is already in simplest form. Since 3³ = 27 < 55 < 64 = 4³, ∛55 lies between 3 and 4: ∛55 ≈ 3.803.
Is ∛55 a rational number?
No: 55 is not the cube of a rational number, and the cube root of a fraction p/q in lowest terms is rational only when p and q are both cubes. So ∛55 is irrational; its decimal never ends and never repeats: ∛55 ≈ 3.803.
