    What is the cube root of 1,125?

    Answer

    ∛1,125 =
    5∛9 ≈ 10.4004

    Real cube root: the only number whose cube is 1,125.

    ≈ — rounded to 4 decimal places. 1,125 is not the cube of a rational number, so ∛1,125 is irrational: its decimal expansion never ends and never repeats.

    Prime factors
    1,125 = 3 × 3 × (5 × 5 × 5) = 3² × 5³
    Take out of the root
    ∛1,125 = ∛(5³ × 9) = 5∛9
    Between cubes
    10³ = 1,000 < 1,125 < 1,331 = 11³, so 10 < ∛1,125 < 11 and ∛1,125 ≈ 10.4004

    FAQ

    What is the cube root of 1,125?

    ∛1,125 = 5∛9 ≈ 10.4004

    How to simplify ∛1,125?

    Factor 1,125 into primes: 1,125 = 3 × 3 × 5 × 5 × 5. Each triple of equal factors is a cube and comes out of the root as one factor; the rest stays under it: ∛1,125 = ∛(5³ × 9) = 5∛9.

    Is ∛1,125 a rational number?

    No: 1,125 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 ∛1,125 is irrational; its decimal never ends and never repeats: ∛1,125 ≈ 10.4004.
