There are two ways to find the square root of a number. The first way is to use a calculator. The second way is to use a method called long division.
To use a calculator, press the square root button and then enter the number you want to find the square root of. The calculator will then give you the answer.
To use the long division method, divide the number you want to find the square root of by the number 2. Then, keep track of the remainders. The square root of the number is the number that, when multiplied by itself, results in the original number and the remainder is the last number in the division.

What is Square Root of Decimal Number
We know that a square root is a number that when multiplied by itself gives the original number. So, the square root of 25 is 5 because 5 multiplied by 5 is 25.
To find the square root of a decimal number, we first need to find the square root of the number’s integer part. We then need to find the square root of the number’s decimal part. We then add the two square roots together.
For example, the square root of 8.6 is 2.8 because 2 multiplied by 2.8 is 8.6. The square root of 0.345 is 0.5 because 0.5 multiplied by 0.5 is 0.345. So, the square root of 8.6 is 2.8 + 0.5 = 3.3.
Steps for Finding the Square Root of Decimal Number with Examples
To find the square root of a decimal number, follow these steps:
1. Write the decimal number as a fraction.
