What is the Square Root of 62?
The square root of a number n is written as √n. This number when squared or multiplied by itself results in the original number n. The square root of 62 can be written in multiple ways
- Radical form: √62
- Decimal form: 7.874
- Exponent form: (62)1/2
Is Square Root of 62 Rational or Irrational?
- 62 is a number that is not a perfect square, meaning it does not have a natural number as its square root.
- Also, its square root cannot be expressed as a fraction of the form p/q which confirms to us that the square root of 62 is an irrational number.
How to Find the Square Root of 62?
There are multiple ways to find the square root of 62-
- Long Division
- Estimation and Approximation

Long Division Method
The square root of 62 by long division method consists of the following steps:
- Step 1: Starting from the right, we will pair up the digits 62 by putting a bar above them. We also pair the 0s in decimals in pairs of 2 from left to right.
- Step 2: Find a number that, when multiplied to itself, gives a product less than or equal to 62. The number 7 fits here as 7 squared gives 49. Dividing 62 by 7 with quotient of 7, we get the remainder as 13.
- Step 3: Drag a pair of 0’s down and fill it next to the remainder to make the dividend 1300.
- Step 4: Double the divisor 7, and enter 14 below with a blank digit on its right. Guess the largest possible digit(X) to fill in the blank and the quotient for which the product of 14X × X results in a value less than or equal to 1300. This will be 8 in this case, so divide 1400 with 168 and write the remainder.
- Step 5: Repeat this process to get the decimal places you want.
Therefore, the square root of 62 = 7.874
Estimation and Approximation
The estimation method gives us an approximate answer and is usually not accurate to more than 1 decimal place. However, it is easy to perform as can be seen under.
- Step 1: Find a perfect square that is smaller than and bigger than 62. In this case, 7 and 8 will work as their squares are 49 and 64.
- Step 2: Writing in terms of inequality: 7 < √62 < 8 = 49 < 62 < 64
- Step 3: Multiply by 10 and write in terms of square roots: √4900 < √6200 < √6400
- Step 4: Move closer to inequality: √6084 < √6200 < √6241 = 78 < 10√62 < 79 = 7.8 < √62 < 7.9
- Step 5: Taking the average of upper and lower limits we get, (7.8 + 7.9)/2 = 7.85
Therefore, we can estimate the square root of 62 ≅ 7.85

- There exists a positive and negative root of 62, 7.874 and -7.874.
- The square root of 62 is an irrational number that is non-terminating.
- What is the square root of 62 up to 6 decimal places(Use Long Division)?
- Find the square root of the following numbers:
Example 1: Jake wants to calculate the side length of his square courtyard in his home. It has an area of 62 square feet.
To find the side of the courtyard, we will have to find the square root of 62. The square root is √62 = 7.874.
Hence, the side length of the courtyard is approximately 7.9 feet.
Example 2: Gary was asked to solve an equation x2 - 62 = 0. Help him find all values of x
x2 - 62 = 0
x2 = 62.
Taking the square root on both sides, we get
x = ±7.874
