How to Find the Square Root of 10 with Formula and Examples
Square Root
The square root of any number gives the same number when the number multiplied by itself.
For example - \[\sqrt{p\times p}\] = \[\sqrt {(p)^{2}}\] = p
Square Root Symbol
The symbol used to denote the square root is "√". It is also known as a radical symbol or radix. The number written under the square root symbol is called the radicand. The square value can be represented in the radical form as well as in decimal form. Square root of 10 can also be represented as a radical of 10.
How to Calculate the Value of a Square Root of 10?
Calculating the root 10 value is a bit complex because the number 10 is not a perfect square as its unit digit is 0. Square root of a number can be easily obtained if the number is in a perfect square. The number is considered as a perfect square if it can be denoted as a product of two equal integers.
For example- 5x5= 25, it is representing the square of a number 5. It is considered as a perfect square as it is stated as a product of two similar integers i.e. 5 x 5 = 25, 6 x 6= 36. It is representing the square of 6. It is even considered as a perfect square as it is stated as a product of two similar integers i.e. 6 x 6.
The number is a perfect square if the unit place of a number ends with 1,4,5,6 or 9
The number is not said to be a perfect square if it ends with 2, 3, 7 or 8.
We can calculate the value of a square root or root 10 values through two methods.
First method to calculate the value of a square root or root 10 value is to use the unit digit of the given number,
The second method to calculate the square root value or root 10 values of the given number is by using a long division method.
What is the Square Root of 10?
The square root of 10 or root 10 is represented in the form of √10. As we know 10 is an even number but not a prime number. Prime numbers are considered as those numbers which have only two factors i.e. 1 and the number itself. For example 2 is a prime number as it has only factors 1 and 2 itself. But number 10 is not a prime number because it has multiple factors like.
1x10 = 10
2 x 5= 10
10 x 1 = 10
5 x 2 = 10
To calculate the square root of value 10, write its factors first
10 = 2 x 5
Square root of 10 can be written in the below format
\[\sqrt 10\] = \[\sqrt 2\] X \[\sqrt 5\]
Common square terms out of the root in the above equation cannot be taken out as it has no common square terms.
\[\sqrt 10\] =\[\sqrt 2\] \[\sqrt 5\]
\[\sqrt 10\] or root 10 is in the radical form. If you want to write it in a decimal form, then substitute approximate values of \[\sqrt 2\] and \[\sqrt 5\] which is 1.414 and 2.236 respectively,
8\[\sqrt 10\] =1.414 x 2.236
\[\sqrt 10\] =3.162
Hence, the value of root 10 or root 10 is 3.162

Solved Example
1. Find the value of √80 + 16√5 , if 3√5+√125 = 17.88
Solution: \[\frac{x}{\sqrt{512}}\] = \[\frac{\sqrt{648}}{x}\]
= 3√5 + √125 = 17.88
= 3√5 + (√25 x √5) = 17.88
= 3√5 + 5√5 = 17.88
= 8√5 = 17.88
= √5 = 17.88/8
= √80 + 16√5 = √16 x √5 + 16 √5
= 4√5 + 16√5 = 20√5
= 20 x 17.88/8 = 44.7
2. Simplify: (√7 -1/√7)2
= (√7 -1/√7)2
= (√7 -1/√7)2
= (√7)2 – 2 x √7 x 1√7 + (1/√7)2
= 7-2 +1/7
= 5 + 1/7
= 36/7
Fun Facts
The Yale Babylonian has a tablet from nearly 4000 years ago that states the square root of 2 out to 9 decimal places by making use of a square and two diagonals.
Communities in Ancient India were making use of square roots since 800 BCE.
An Indian Mathematician from the 9th century named Mahavira is the first person to announce that negative square roots do not take place.
Procedure to determine the square root is outlined in the Chinese book, Writings on Reckoning, written in around 200 BCE during the Han Dynasty.

FAQs on What Is the Square Root of 10
1. What is the square root of 10?
The square root of 10 is √10 ≈ 3.1623. This means that 3.1623 × 3.1623 ≈ 10. Since 10 is not a perfect square, its square root is not a whole number. The exact value is written as √10, while 3.1623 is its decimal approximation rounded to four decimal places.
2. Is √10 a rational or irrational number?
√10 is an irrational number because it cannot be expressed as a simple fraction of two integers. Its decimal form, 3.162277..., continues forever without repeating. Since 10 is not a perfect square, its square root is always irrational.
3. How do you simplify the square root of 10?
The square root of 10 cannot be simplified further because 10 has no perfect square factors other than 1.
- Prime factorization of 10 = 2 × 5
- Neither 2 nor 5 is a perfect square
4. How do you find the decimal value of √10?
The decimal value of √10 ≈ 3.1623 can be found using a calculator or long division method.
- Enter √10 in a calculator
- The result is approximately 3.162277...
5. What is √10 rounded to two decimal places?
√10 rounded to two decimal places is 3.16. Since √10 ≈ 3.1623, we look at the third decimal digit (2). Because it is less than 5, we round down, giving the final answer as 3.16.
6. What is the value of √10 squared?
(√10)² = 10 because squaring a square root returns the original number. This follows the identity:
- (√a)² = a
7. Is √10 a real number?
√10 is a real number because it represents a positive value on the number line. Since 10 is positive, its square root is defined within the set of real numbers. Therefore, √10 belongs to both the real numbers and the irrational numbers.
8. What is the square root of negative 10?
The square root of negative 10 is √(-10) = i√10, which is an imaginary number. In complex numbers,
- i = √(-1)
9. Between which two integers does √10 lie?
√10 lies between 3 and 4 because 3² = 9 and 4² = 16. Since 10 is greater than 9 but less than 16, its square root must lie between 3 and 4. Numerically, √10 ≈ 3.1623.
10. How is √10 used in geometry?
√10 appears in geometry when using the Pythagorean theorem to find the length of a hypotenuse. For example:
- If a right triangle has legs 1 and 3,
- Hypotenuse² = 1² + 3² = 1 + 9 = 10
- Hypotenuse = √10
