FAQ
What is the cube root of 149?
∛149 ≈ 5.3015
Can ∛149 be simplified?
No: no prime appears three times in 149, so its only cube factor is 1 and ∛149 is already in simplest form. Since 5³ = 125 < 149 < 216 = 6³, ∛149 lies between 5 and 6: ∛149 ≈ 5.3015.
Is ∛149 a rational number?
No: 149 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 ∛149 is irrational; its decimal never ends and never repeats: ∛149 ≈ 5.3015.
