What is the cube root of 25?
Answer
∛25 ≈
2.924
Real cube root: the only number whose cube is 25.
≈ — rounded to 4 decimal places. 25 is not the cube of a rational number, so ∛25 is irrational: its decimal expansion never ends and never repeats.
- Prime factors
- 25 = 5 × 5 = 5²
- Take out of the root
- No prime appears three times, so ∛25 is already in simplest form.
- Between cubes
- 2³ = 8 < 25 < 27 = 3³, so 2 < ∛25 < 3 and ∛25 ≈ 2.924

FAQ
What is the cube root of 25?
∛25 ≈ 2.924
Can ∛25 be simplified?
No: no prime appears three times in 25, so its only cube factor is 1 and ∛25 is already in simplest form. Since 2³ = 8 < 25 < 27 = 3³, ∛25 lies between 2 and 3: ∛25 ≈ 2.924.
Is ∛25 a rational number?
No: 25 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 ∛25 is irrational; its decimal never ends and never repeats: ∛25 ≈ 2.924.
