What is the cube root of 700?

Answer

∛700 ≈
8.879

Real cube root: the only number whose cube is 700.

≈ — rounded to 4 decimal places. 700 is not the cube of a rational number, so ∛700 is irrational: its decimal expansion never ends and never repeats.

Prime factors
700 = 2 × 2 × 5 × 5 × 7 = 2² × 5² × 7
Take out of the root
No prime appears three times, so ∛700 is already in simplest form.
Between cubes
8³ = 512 < 700 < 729 = 9³, so 8 < ∛700 < 9 and ∛700 ≈ 8.879
