# What is the square root called? Method to find the square root (Vargmool)

**Definition of square root:- **The square root of a given number is the number whose square root gives the given number. To represent the square root, the following symbol is placed on the given number. **” **is applied.

**Example:- **Square root of number 25 = 25 = 5

### Method to find square root / How to find square root?

It is extracted by two methods, which are as follows-

#### 1.Factor Method

While finding the square root of a given number by this method, first we break that number as a factor and then make a pair of equal number. After this we multiply by taking one number of each pair, then the required square root of the given number is obtained.

**solution:-**

#### 2.Division Method

While finding the square root of a given number by this method, first of all we make pairs of two digits from the right side of that number. If only one digit is left on the left side of the number or a pair of digits is left, then start solving from that digit and after that the added digit is dropped together while solving.

**For example –** Let’s say +3 and -3 are square roots of 9. Now, how do we know this? 3 x 3 = 9 or this (-3)^{2} Can also be = (-3) x (-3) = 9. A real number that is positive has a positive root. It is called x−−√ . where x refers to the number whose square root is to be found and the value of x is called the radix.

The symbol is called the radix or it is also known as the radix symbol. Now, the root square root of 49 is 7 and it is called 7^{2} = 7 x 7 = 49, and the number 7 is a non-negative number. Here, the radius is 49.

### What will be the square root of 40?

2 x 2 x 2 x 5 are multiples of 40.

We can also say that the multiples of 40 are 10 and 4. The square root of four is equal to 2. Now we have 10 left. Although we know that 10 is not a perfect square, we can still find the root of 10 with the help of long division method.
