    What is the cube root of 279?

    Answer

    ∛279 ≈
    6.5343

    Real cube root: the only number whose cube is 279.

    ≈ — rounded to 4 decimal places. 279 is not the cube of a rational number, so ∛279 is irrational: its decimal expansion never ends and never repeats.

    Prime factors
    279 = 3 × 3 × 31 = 3² × 31
    Take out of the root
    No prime appears three times, so ∛279 is already in simplest form.
    Between cubes
    6³ = 216 < 279 < 343 = 7³, so 6 < ∛279 < 7 and ∛279 ≈ 6.5343

    FAQ

    What is the cube root of 279?

    ∛279 ≈ 6.5343

    Can ∛279 be simplified?

    No: no prime appears three times in 279, so its only cube factor is 1 and ∛279 is already in simplest form. Since 6³ = 216 < 279 < 343 = 7³, ∛279 lies between 6 and 7: ∛279 ≈ 6.5343.

    Is ∛279 a rational number?

    No: 279 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 ∛279 is irrational; its decimal never ends and never repeats: ∛279 ≈ 6.5343.
