What is the cube root of 900?

Answer

∛900 ≈
9.6549

Real cube root: the only number whose cube is 900.

≈ — rounded to 4 decimal places. 900 is not the cube of a rational number, so ∛900 is irrational: its decimal expansion never ends and never repeats.

Prime factors
900 = 2 × 2 × 3 × 3 × 5 × 5 = 2² × 3² × 5²
Take out of the root
No prime appears three times, so ∛900 is already in simplest form.
Between cubes
9³ = 729 < 900 < 1,000 = 10³, so 9 < ∛900 < 10 and ∛900 ≈ 9.6549

Can ∛900 be simplified?

No: no prime appears three times in 900, so its only cube factor is 1 and ∛900 is already in simplest form. Since 9³ = 729 < 900 < 1,000 = 10³, ∛900 lies between 9 and 10: ∛900 ≈ 9.6549.

Is ∛900 a rational number?

No: 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 ∛900 is irrational; its decimal never ends and never repeats: ∛900 ≈ 9.6549.
