Cube Roots
The number c is the cube root of a, written ![\sqrt[3]{a}](https://mymathangels.com/wp-content/ql-cache/quicklatex.com-1e8db6b7ec320a24ce33551c0ef383fb_l3.png "Rendered by QuickLaTeX.com")
if the third power of c is a – that is , if c3 = a, then = c.
For example:
2 is the cube root of 8 because 23 = 2.2.2 = 8
Every real number has exactly one cube root in the system of real
numbers. The symbol represents the cube root of a.
