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: 52 = ( 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.

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 in2. 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 = 6a2 = 150 in2
⇒ a = ±√25 in
Since length can't be negative,
⇒ a = √25
We know that the square root of 25 is 5.
⇒ a = 5 in
