In this article, we will explore the mystery behind the square root of 84.

What is Square Root?

Before we delve into the square root of 84, let's first understand what a square root is. As mentioned earlier, a square root is a value that, when multiplied by itself, gives the original number. In other words, it is the opposite of squaring a number. For instance, the square of 4 is 16, and the square root of 16 is 4.

How to Find Square Root of 84?

To find the square root of any number, you can use different methods such as long division, prime factorization, or estimation. However, the most common method is using a calculator. To find the square root of 84 using a calculator, you need to press the square root button and enter 84, which will give you the answer of approximately 9.165.

Is the Square Root of 84 Rational or Irrational?

A rational number is a number that can be expressed as a ratio of two integers. An irrational number, on the other hand, cannot be expressed as a ratio of two integers. The square root of 84 is an irrational number since it cannot be expressed as a ratio of two integers.

Why is the Square Root of 84 Irrational?

To understand why the square root of 84 is irrational, we need to look at its prime factorization. Prime factorization is the process of breaking down a number into its prime factors. The prime factorization of 84 is 2 x 2 x 3 x 7. When we take the square root of 84, we are essentially looking for two numbers that, when multiplied by each other, give us 84. However, none of the factors can be multiplied by themselves to give us 84. Therefore, the square root of 84 is an irrational number.

What are Some Properties of Irrational Numbers?

Irrational numbers have some unique properties that differentiate them from rational numbers. For instance, they cannot be expressed as fractions, and their decimal expansions are non-repeating and non-terminating. Additionally, the sum, difference, product, or quotient of two irrational numbers is not necessarily irrational.

Applications of the Square Root of 84

Although the square root of 84 might seem like a random number, it has its applications in different fields such as engineering, physics, and computer science.
