## Square Root How To Calculate – Super easy guide

Calculating the square root of a number may seem intimidating at first, but it’s actually a fairly simple concept once you understand the basic principles. In this blog post, we’ll break down the steps for calculating the square root of a number and provide some helpful tips and tricks along the way.

## What a Square Root actually is

First, let’s start by defining what a square root actually is. Simply put, the square root of a number is a value that, when multiplied by itself, equals the original number.

**For example,** the square root of 25 is 5, because 5 x 5 = 25. Similarly, the square root of 100 is 10, because 10 x 10 = 100.

## 3 Steps for calculating Square Root

Now that we have a basic understanding of square roots, let’s look at the steps for calculating them.

- First, we need to find two perfect squares that the original number falls between. For example, if we want to find the square root of 38, we would look for two perfect squares that 38 falls between. In this case, those numbers would be 36 (6 x 6) and 49 (7 x 7).
- Second, we need to find the average of these two perfect squares. In the case of 38, that would be (36 + 49) / 2 = 42.5.
- Third, we need to find the square root of this average number. Since 42.5 is not a perfect square, we need to use an estimation method to find its square root. One common method is to use a table of perfect squares to find the two closest perfect squares to 42.5, which in this case would be 36 (6 x 6) and 49 (7 x 7).

From here, we can use a simple trick to estimate the square root of 42.5. Since 42.5 falls halfway between 36 and 49, we can average the square roots of these two numbers to estimate the square root of 42.5. In this case, that would be (6 + 7) / 2 = 6.5.

Now that we have an estimated value for the square root of 42.5, we can use this value to calculate the square root of 38. Since the square root of 38 is between the square root of 36 and the square root of 49, we can use our estimated value of 6.5 as a starting point and then make adjustments based on whether the square of 6.5 is less than or greater than 38.

In this case, we can see that 6.5 x 6.5 = 42.25, which is slightly less than 38. This means that the square root of 38 is slightly greater than 6.5. We can use this information to make a more accurate estimate of the square root of 38 by performing the same calculation with a slightly higher number, such as 6.6.

After repeating this process several times, we can eventually arrive at a very accurate estimate for the square root of 38, which in this case would be approximately 6.082762530298219.

## Perfect Square RootsTable

Here’s a table of perfect squares to help you get started:

Number | Square | Square Root |
---|---|---|

1 | 1 | 1 |

2 | 4 | 2 |

3 | 9 | 3 |

4 | 16 | 4 |

5 | 25 | 5 |

6 | 36 | 6 |

7 | 49 | 7 |

8 | 64 | 8 |

9 | 81 | 9 |

10 | 100 | 10 |

With this table and the methods outlined above, you should be able to easily estimate the square root of any number. Happy calculating!

In summary, calculating the square root of a number involves finding two perfect squares that the original number falls between, finding the average of these two numbers, and then using estimation methods to find the square root of this average number. By repeating this process and making adjustments based on the results, we can arrive at a very accurate estimate for the square root of the original number.

Hopefully this breakdown has helped to demystify the process of calculating square roots. With a little practice and some patience, you’ll be able to easily calculate the square root of any number in no time!

## Square Root Calculators

If you want to quickly and easily calculate the square root of a number, you can use an online square root calculator or a calculator app on your smartphone. These tools allow you to enter a number and instantly see its square root without having to do any calculations yourself.

To use an online square root calculator, simply go to a search engine and type in “square root calculator.” This will bring up a list of websites that offer this tool, such as calculators.org or calculator-1.com. Click on one of these websites and then enter the number that you want to find the square root of into the designated field. The calculator will then display the square root of the number in real-time.

To use a calculator app on your smartphone, simply open the app and enter the number that you want to find the square root of. Most calculator apps have a button labeled “√” that you can use to calculate the square root of a number. Simply press this button after entering the number and the calculator will display the square root in the main display window.

In addition to using online calculators or calculator apps, you can also calculate square roots using a scientific calculator. Most scientific calculators have a button labeled “√” that you can use to calculate the square root of a number. Simply enter the number that you want to find the square root of and then press the “√” button to display the result.
