## Is the square root of 8 closer to 2 or 3?

Hence the (positive) square root of 8 is somewhere between 2 and 3. Since 8 is much closer to 9= 32 than 4= 22, we can deduce that the closest integer to the square root is 3.

## What is 9 The square root of?

The square root of a number is a number that, when multiplied by itself, equals the desired value. So, for example, the square root of 49 is 7 (7×7=49). List of Perfect Squares.

NUMBER | SQUARE | SQUARE ROOT |
---|---|---|

6 | 36 | 2.449 |

7 | 49 | 2.646 |

8 | 64 | 2.828 |

9 | 81 | 3.000 |

## Why is 9 The square root of 81?

Explanation: 81 = 9 ⋅ 9 then the square root of √ 81 = 9. Because the double multiplication for the same sign is always positive, the square root is also valid with the other sign 81 =(− 9 )⋅(− 9 ) then √ 81 =− 9 and we can say that √ 81 =± 9.
