What is the cube root of 730?
Answer
∛730 ≈
9.0041
Real cube root: the only number whose cube is 730.
≈ — rounded to 4 decimal places. 730 is not the cube of a rational number, so ∛730 is irrational: its decimal expansion never ends and never repeats.
- Prime factors
- 730 = 2 × 5 × 73
- Take out of the root
- No prime appears three times, so ∛730 is already in simplest form.
- Between cubes
- 9³ = 729 < 730 < 1,000 = 10³, so 9 < ∛730 < 10 and ∛730 ≈ 9.0041

FAQ
What is the cube root of 730?
∛730 ≈ 9.0041
Can ∛730 be simplified?
No: no prime appears three times in 730, so its only cube factor is 1 and ∛730 is already in simplest form. Since 9³ = 729 < 730 < 1,000 = 10³, ∛730 lies between 9 and 10: ∛730 ≈ 9.0041.
Is ∛730 a rational number?
No: 730 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 ∛730 is irrational; its decimal never ends and never repeats: ∛730 ≈ 9.0041.
