Frequently Asked Questions
What is a cube root?
A cube root of a number x is a value that, when multiplied by itself three times, gives x. For example, the cube root of 8 is 2 because 2 × 2 × 2 = 8. It's written as ∛x or x^(1/3).
How do you calculate cube roots of negative numbers?
The cube root of a negative number is negative. For example, ∛(-8) = -2 because (-2) × (-2) × (-2) = -8. Unlike square roots, cube roots of negative numbers are real numbers.
What's the difference between cube root and square root?
A square root uses index 2 (√x), while cube root uses index 3 (∛x). Square roots of negative numbers are imaginary, but cube roots of negative numbers are real. Cube root is the inverse operation of cubing a number.
