What Is the Square Root of 25?
Let us first understand the meaning of the square root. The square root of a number is the number that, when multiplied to itself, gives the product as the original number. Consider the example: 5^{2} = ^{ }( 5 × 5) = 25.
Here 5 is called the square root of 25. 25 is a perfect square. So the square root of 25 is 5.
Is Square Root of 25 Rational or Irrational?
A rational number can be expressed in the form of p/q. Because √25 = 5 and 5 can be written in the form of a fraction 5/1. It proves that √25 is rational.
How to Find the Square Root of 25?
We can find the square root of 25 using various methods. If you want to learn more about each of these methods, click here. Since we could find that 25 is a perfect square, we can find its square root using long division.
The square root of 25 can be found using the long division as follows:
Since the remainder is 0, we do not need to proceed with long division further and we consider the quotient (which is 5) as the result.

Solved Examples of 25 Solved Examples

Example 1 Kate wanted to check if square root of 25 can be found using repeated subtraction method. Let's help her out!
Solution:
In the repeated subtraction method, we subtract the odd numbers starting from 1 until we get a 0.
25 − 1 = 24
24 − 3 = 21
21 − 5 = 16
16 − 7 = 9
9 − 9 = 0Hence, √25 = 5.

Example 2: Help Kylie find the square root of 25 using prime factorization.
Solution:
Prime factorization of 25 = 5 × 5
√25 = √(5)(5) = 5

Example: If the surface area of a cube is 150 in^{2}. Find the length of the side of the cube.
Solution:
Let 'a' be the length of the side of the cube.
⇒ Area of the cube = 6a^{2} = 150 in^{2}
⇒ a = ±√25 in
Since length can't be negative,
⇒ a = √25
We know that the square root of 25 is 5.
⇒ a = 5 in
