    What is the cube root of 0.69?

    Answer

    ∛0.69 ≈
    0.8837

    Real cube root: the only number whose cube is 0.69.

    ≈ — rounded to 4 decimal places. 0.69 is not the cube of a rational number, so ∛0.69 is irrational: its decimal expansion never ends and never repeats.

    Between cubes
    0.8³ = 0.512 < 0.69 < 0.729 = 0.9³, so 0.8 < ∛0.69 < 0.9 and ∛0.69 ≈ 0.8837

    FAQ

    What is the cube root of 0.69?

    ∛0.69 ≈ 0.8837

    How to find ∛0.69 without a calculator?

    Bracket it between cubes: 0.8³ = 0.512 < 0.69 < 0.729 = 0.9³, so ∛0.69 lies between 0.8 and 0.9. Narrowing the bracket digit by digit gives ∛0.69 ≈ 0.8837; 0.69 is not the cube of a decimal, so the root never ends.

    Is ∛0.69 a rational number?

    No: 0.69 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 ∛0.69 is irrational; its decimal never ends and never repeats: ∛0.69 ≈ 0.8837.
