What is the cube root of 290?
Answer
∛290 ≈
6.6191
Real cube root: the only number whose cube is 290.
≈ — rounded to 4 decimal places. 290 is not the cube of a rational number, so ∛290 is irrational: its decimal expansion never ends and never repeats.
- Prime factors
- 290 = 2 × 5 × 29
- Take out of the root
- No prime appears three times, so ∛290 is already in simplest form.
- Between cubes
- 6³ = 216 < 290 < 343 = 7³, so 6 < ∛290 < 7 and ∛290 ≈ 6.6191

FAQ
What is the cube root of 290?
∛290 ≈ 6.6191
Can ∛290 be simplified?
No: no prime appears three times in 290, so its only cube factor is 1 and ∛290 is already in simplest form. Since 6³ = 216 < 290 < 343 = 7³, ∛290 lies between 6 and 7: ∛290 ≈ 6.6191.
Is ∛290 a rational number?
No: 290 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 ∛290 is irrational; its decimal never ends and never repeats: ∛290 ≈ 6.6191.
