### Cube Roots

We already know that a number multiplied by itself three times is called a cube (refer to Cubes)

The cube root works the other way: where you have the resulting cube, and you want to find the number that is multiplied by itself three times to get the cube

Cube | 3^{3} = 3 × 3 × 3 = 27 |

Cube root | ^{3}√27 = 3 |

Cube root can also be written as | 27^{1/3} = 3 |

#### • Examples

Cube root | Cube | |

1. | ^{3}√8 = 2 | 2^{3} = 2 × 2 × 2 = 8 |

2. | ^{3}√27 = 3 | 3^{3} = 3 × 3 × 3 = 27 |

3. | ^{3}√64 = 4 | 4^{3} = 4 × 4 × 4 = 64 |

4. | ^{3}√125 = 5 | 5^{3} = 5 × 5 × 5 = 125 |
