What Is The Positive Square Root Of 25?$\sqrt{25} =$
Introduction
In mathematics, the square root of a number is a value that, when multiplied by itself, gives the original number. The square root of a number can be either positive or negative, but in this article, we will focus on finding the positive square root of 25.
Understanding Square Roots
A square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4, because 4 multiplied by 4 equals 16. The square root of a number can be represented by the symbol √, and it is often denoted as the nth root of a number, where n is the power to which the number is raised.
Finding the Positive Square Root of 25
To find the positive square root of 25, we need to find a number that, when multiplied by itself, gives 25. We can start by listing the perfect squares of numbers and see if any of them equal 25.
| Number | Perfect Square |
|---|---|
| 1 | 1 |
| 2 | 4 |
| 3 | 9 |
| 4 | 16 |
| 5 | 25 |
As we can see from the table above, the perfect square of 5 is 25. Therefore, the positive square root of 25 is 5.
Why is the Positive Square Root of 25 Important?
The positive square root of 25 is an important concept in mathematics because it is used in many real-world applications. For example, in geometry, the square root of a number is used to find the length of the sides of a square or a rectangle. In algebra, the square root of a number is used to solve equations and inequalities.
Real-World Applications of the Positive Square Root of 25
The positive square root of 25 has many real-world applications. For example:
- Geometry: The square root of a number is used to find the length of the sides of a square or a rectangle. For example, if we have a square with a side length of 5, the area of the square is 25, and the square root of 25 is 5.
