What is the cube root of 39?
Answer
∛39 ≈
3.3912
Real cube root: the only number whose cube is 39.
≈ — rounded to 4 decimal places. 39 is not the cube of a rational number, so ∛39 is irrational: its decimal expansion never ends and never repeats.
- Prime factors
- 39 = 3 × 13
- Take out of the root
- No prime appears three times, so ∛39 is already in simplest form.
- Between cubes
- 3³ = 27 < 39 < 64 = 4³, so 3 < ∛39 < 4 and ∛39 ≈ 3.3912

FAQ
What is the cube root of 39?
∛39 ≈ 3.3912
Can ∛39 be simplified?
No: no prime appears three times in 39, so its only cube factor is 1 and ∛39 is already in simplest form. Since 3³ = 27 < 39 < 64 = 4³, ∛39 lies between 3 and 4: ∛39 ≈ 3.3912.
Is ∛39 a rational number?
No: 39 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 ∛39 is irrational; its decimal never ends and never repeats: ∛39 ≈ 3.3912.
