## How to Calculate Square Root of 2?

For thousands of years, mathematicians have been enthralled by the square root of 2, a mathematical constant. Ancient civilizations like the Greeks and the Egyptians, who utilised it in their geometrical and mathematical computations, are credited with its invention. Since the square root of 2 is an irrational integer, it cannot be written as a straightforward fraction and its decimal representation never ends. Despite this, the square root of 2 has a distinct position in mathematics and is utilised in a wide range of subjects, including calculus, geometry, and trigonometry. We will look at the definition, characteristics, and uses of the square root of 2, as well as its historical importance and effects on mathematics, in this blog.

## Definition and Properties of the Square Root of 2

The square root of 2 is a mathematical constant that is defined as the positive real number that, when multiplied by itself, equals 2. Symbolically, it can be represented as √2. It is a fundamental constant in mathematics that has many unique properties.
One of its important properties is that it is an irrational number, meaning that it cannot be expressed as a simple fraction. Its decimal representation goes on forever without repeating, making it a non-repeating, non-terminating decimal. This property makes it useful in mathematics and other fields where precision is crucial.
Another property of the square root of 2 is its non-periodicity. This means that its decimal representation does not repeat in a predictable pattern, making it different from other repeating decimals.

The square root of 2 also has some interesting geometric applications. For example, in Euclidean geometry, it is used to calculate the diagonal length of a square with sides of length 1. In trigonometry, it is used in the calculation of trigonometric functions, such as sine and cosine.

In summary, the square root of 2 is a mathematical constant with unique properties such as being an irrational number and having non-periodic decimal representation. These properties make it useful in a variety of mathematical applications and calculations

## How to Find Square Root of 2 By Long Division Method?

Now, let’s look at how to find the square root of 2 using the method of division. You can begin by utilizing one of the most common methods, which is called division. The following procedures are included in this method: In the first step of this method, you are required to make an estimate, which indicates that you have selected a number that is relatively close by locating at least two roots that are perfect. Your number is between those values because those roots have caused it to be that way.

1st Step: The 2nd step is to divide the number by one of the square roots that you found earlier.

2nd Step: Once you begin and continue with the process of division, you will need to take the average of the result of step 2 and the root.
3rd Step: This will be your final answer. And lastly, you can use the result that you get in step 3 to repeat steps 2 and 3 as many times as necessary until you arrive at a number that satisfies your requirements in terms of how accurate it is.
