## How to Find the Square Root of 19?

The square root of 19 is found using the following steps:

**Step 1**: Check whether the number is a perfect square or not.

19 is not a perfect square as it cannot be broken down into a product of two same numbers.

**Step 2**: Once the number is checked, the following are the processes required to be followed:If the number is a perfect square, it can be written in this format

**√**x2 = x.If the number is not a perfect square, the square root is found using the long division method. It can also be written in its simplified radical form of the square root.

In this case, 19 is not a perfect square, hence its square root is found using the long division method. The simplified radical form of the square root of 19 is given below.

### Simplified Radical Form of Square Root of 34

19 can be written as a product 1 and 19. It is given as:

**√**19 = **√**1 × 19

19 is not a perfect square, hence it remains within roots. Simplified radical form of square root of 19 is **√**19.

### Square Root of 34 by Long Division Method

The value of the square root of 19 by long division method consists of the following steps:

**Step 1**: Starting from the right, we will pair up the digits by putting a bar above them.

**Step 2**: Find a number such that when you multiply it with itself, the product is less than or equal to 19. So, the number is 4. Putting the divisor as 4, we get the quotient as 4 and the remainder as 3.

**Step 3**: Double the quotient and enter it with a blank on its right. Guess the largest possible digit to fill the blank which will also become the new digit in the quotient, such that when the new divisor is multiplied to the new quotient the product is less than or equal to the dividend. Divide and write the remainder. Repeat this process to get the decimal places you want.
