    What is the cube root of 86?

    Answer

    ∛86 ≈
    4.414

    Real cube root: the only number whose cube is 86.

    ≈ — rounded to 4 decimal places. 86 is not the cube of a rational number, so ∛86 is irrational: its decimal expansion never ends and never repeats.

    Prime factors
    86 = 2 × 43
    Take out of the root
    No prime appears three times, so ∛86 is already in simplest form.
    Between cubes
    4³ = 64 < 86 < 125 = 5³, so 4 < ∛86 < 5 and ∛86 ≈ 4.414

    FAQ

    What is the cube root of 86?

    ∛86 ≈ 4.414

    Can ∛86 be simplified?

    No: no prime appears three times in 86, so its only cube factor is 1 and ∛86 is already in simplest form. Since 4³ = 64 < 86 < 125 = 5³, ∛86 lies between 4 and 5: ∛86 ≈ 4.414.

    Is ∛86 a rational number?

    No: 86 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 ∛86 is irrational; its decimal never ends and never repeats: ∛86 ≈ 4.414.
