What is the cube root of 4,045?
Answer
∛4,045 ≈
15.9333
Real cube root: the only number whose cube is 4,045.
≈ — rounded to 4 decimal places. 4,045 is not the cube of a rational number, so ∛4,045 is irrational: its decimal expansion never ends and never repeats.
- Prime factors
- 4,045 = 5 × 809
- Take out of the root
- No prime appears three times, so ∛4,045 is already in simplest form.
- Between cubes
- 15³ = 3,375 < 4,045 < 4,096 = 16³, so 15 < ∛4,045 < 16 and ∛4,045 ≈ 15.9333

FAQ
What is the cube root of 4,045?
∛4,045 ≈ 15.9333
Can ∛4,045 be simplified?
No: no prime appears three times in 4,045, so its only cube factor is 1 and ∛4,045 is already in simplest form. Since 15³ = 3,375 < 4,045 < 4,096 = 16³, ∛4,045 lies between 15 and 16: ∛4,045 ≈ 15.9333.
Is ∛4,045 a rational number?
No: 4,045 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 ∛4,045 is irrational; its decimal never ends and never repeats: ∛4,045 ≈ 15.9333.
