What Is the Square Root of 5? How to Find the Square Root of 5?
The square root of 5 is 2.236. The square root of a number is which, when multiplied by itself gives the product of the original number. The square root is denoted as, for radical form √5 and for exponential form 51/2 or (5)0.5.
To understand the definition of square root better let’s take an example. The square root of 36 is 6. 6 when multiplied itself gives the number. Since 36 is a perfect square number. For the numbers that are not perfect squares, the root is found using the long division method. 5 is considered a non-square number still, finding a square is also possible but they are not whole numbers.
Finding the square root for non-perfect numbers is possible using the long division method.

Steps to find the square root of 5
- Step 1: Find the smallest integer that can divide the number. The integer 2 is the number that is closest to 5 and can be used as a divisor
- Step 2: Keep following the long division by using the divisor and dividend.
- Step 3: When the particular number of satisfaction is reached the quotient is the square root of the number. Hence, √5 = 2.23.
Solved examples
Q 1: What is the square root of 5?
A 1: √5 = 2.23
Q 2: Find the square root of 2.
A 2: √2 = 1.4142
Q 3: Find the square root of 3.
A 3: Hence, the √3 = 1.732
Q 4: Find the square root of 121.
A4: 121 = 11 × 11
121 = 112
Hence, the √121 = 11
Q5: what is the square root of 10?
A5: Factors of 10 = 2× 5
Since there is no square root let us take square root on both sides
√10 = √2 ×√5
The root of√ 10 = 1.414 ×2.236
Hence, √10 = 3.162.
