Introduction

Mathematics is a fascinating subject that involves the study of numbers, quantities, and shapes. It is a fundamental tool for problem-solving, critical thinking, and logical reasoning. In this article, we will delve into the world of mathematics and explore the concept of square roots, specifically the square root of 130.

What is a Square Root?

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 is denoted by the symbol √.

Calculating the Square Root of 130

To calculate the square root of 130, we can use a calculator or a mathematical formula. Using a calculator, we find that the square root of 130 is approximately 11.40.

The Integers Closest to the Square Root of 130

Now that we have calculated the square root of 130, we need to find the integers that are closest to this value. The integers closest to 11.40 are 11 and 12.

The Statement

The statement we are given is: $\square \ \textless \ \sqrt{130} \ \textless \ \square$ . Using the integers we found earlier, we can complete the statement as follows:

11 < √130 < 12

Why is this Statement True?

This statement is true because the square root of 130 is approximately 11.40, which is between the integers 11 and 12. In other words, the square root of 130 is greater than 11 and less than 12.

The Importance of Square Roots in Mathematics

Square roots are an essential concept in mathematics, with applications in various fields such as algebra, geometry, and trigonometry. They are used to solve equations, calculate distances, and model real-world phenomena.
