    What is the cube root of 158?

    Answer

    ∛158 ≈
    5.4061

    Real cube root: the only number whose cube is 158.

    ≈ — rounded to 4 decimal places. 158 is not the cube of a rational number, so ∛158 is irrational: its decimal expansion never ends and never repeats.

    Prime factors
    158 = 2 × 79
    Take out of the root
    No prime appears three times, so ∛158 is already in simplest form.
    Between cubes
    5³ = 125 < 158 < 216 = 6³, so 5 < ∛158 < 6 and ∛158 ≈ 5.4061

    FAQ

    What is the cube root of 158?

    ∛158 ≈ 5.4061

    Can ∛158 be simplified?

    No: no prime appears three times in 158, so its only cube factor is 1 and ∛158 is already in simplest form. Since 5³ = 125 < 158 < 216 = 6³, ∛158 lies between 5 and 6: ∛158 ≈ 5.4061.

    Is ∛158 a rational number?

    No: 158 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 ∛158 is irrational; its decimal never ends and never repeats: ∛158 ≈ 5.4061.
