What is the cube root of 23?
Answer
∛23 ≈
2.8439
Real cube root: the only number whose cube is 23.
≈ — rounded to 4 decimal places. 23 is not the cube of a rational number, so ∛23 is irrational: its decimal expansion never ends and never repeats.
- Prime factors
- 23 is a prime number: no triple of equal factors.
- Between cubes
- 2³ = 8 < 23 < 27 = 3³, so 2 < ∛23 < 3 and ∛23 ≈ 2.8439

FAQ
What is the cube root of 23?
∛23 ≈ 2.8439
Can ∛23 be simplified?
No: no prime appears three times in 23, so its only cube factor is 1 and ∛23 is already in simplest form. Since 2³ = 8 < 23 < 27 = 3³, ∛23 lies between 2 and 3: ∛23 ≈ 2.8439.
Is ∛23 a rational number?
No: 23 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 ∛23 is irrational; its decimal never ends and never repeats: ∛23 ≈ 2.8439.
