What is the cube root of 4,900?
Answer
∛4,900 ≈
16.985
Real cube root: the only number whose cube is 4,900.
≈ — rounded to 4 decimal places. 4,900 is not the cube of a rational number, so ∛4,900 is irrational: its decimal expansion never ends and never repeats.
- Prime factors
- 4,900 = 2 × 2 × 5 × 5 × 7 × 7 = 2² × 5² × 7²
- Take out of the root
- No prime appears three times, so ∛4,900 is already in simplest form.
- Between cubes
- 16³ = 4,096 < 4,900 < 4,913 = 17³, so 16 < ∛4,900 < 17 and ∛4,900 ≈ 16.985

FAQ
What is the cube root of 4,900?
∛4,900 ≈ 16.985
Can ∛4,900 be simplified?
No: no prime appears three times in 4,900, so its only cube factor is 1 and ∛4,900 is already in simplest form. Since 16³ = 4,096 < 4,900 < 4,913 = 17³, ∛4,900 lies between 16 and 17: ∛4,900 ≈ 16.985.
Is ∛4,900 a rational number?
No: 4,900 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 ∛4,900 is irrational; its decimal never ends and never repeats: ∛4,900 ≈ 16.985.
