Calculate cube roots and visualize cubic relationships
The cube root of a number x is a number y such that y³ = x. For example, the cube root of 27 is 3 because 3 × 3 × 3 = 27.
3 × 3 × 3 = 27
or
(3)³ = 27

Alright, so here’s the deal: a cube root is just the number you gotta multiply by itself three times to get back to your original number. Like, if you’re staring at 27 and you’re wondering what its cube root is—think 3. Because, yeah, 3 × 3 × 3 = 27. Simple, right?
Here’s how you write the cube root of a number x:
³√x or, if you’re feeling fancy, x^(1/3)
