Introduction

As a math concept, square roots can seem daunting and confusing for some. However, understanding what a square root is and how to calculate it can go a long way in helping one feel more comfortable with math problems that involve them. In this article, we will explore the square root of 85 and how to calculate it.

What is a square root?

A square root is a mathematical operation that seeks to determine what number multiplied by itself results in a given number. For example, the square root of 25 is 5 because 5 x 5 = 25. Square roots are written using the symbol √, which is called a radical sign.

Calculating the square root of 85

To calculate the square root of 85, we need to find the number that, when multiplied by itself, results in 85. We can do this through a process called prime factorization, where we break down 85 into its prime factors.

Prime factorization of 85

To find the prime factorization of 85, we start by dividing it by the smallest prime number, which is 2. We find that 2 does not divide evenly into 85, so we move on to the next smallest prime number, which is 3. Dividing 85 by 3 gives us 28 with a remainder of 1. We continue this process until we reach the largest prime number that divides into 85, which is 17. So, the prime factorization of 85 is 5 x 17.

Simplifying the square root of 85

Now that we know the prime factorization of 85, we can simplify the square root of 85 by breaking it down into its factors. This is because the square root of a product is equal to the product of the square roots of each factor. So, we can write the square root of 85 as the square root of 5 times the square root of 17.

Approximating the square root of 85

If we do not want to simplify the square root of 85 or if we need to find an approximate value for it, we can use a calculator or estimation techniques. One way to estimate the square root of 85 is to compare it to the square roots of nearby perfect squares. The nearest perfect squares to 85 are 81 (which has a square root of 9) and 100 (which has a square root of 10). Since 85 is closer to 81 than 100, we can estimate that the square root of 85 is slightly less than 9.5.

Real-world applications of square roots

Square roots are used in many real-world situations, such as in construction, engineering, and finance. For example, when calculating the length of a diagonal in a square or rectangular building, we need to use the Pythagorean theorem, which involves finding the square root of a sum of squares. Square roots also play a role in determining interest rates on loans and investments, as well as in measuring distances and calculating speeds in physics and astronomy.

Conclusion

In summary, the square root of 85 is equal to the square root of 5 times the square root of 17. By understanding the concept of prime factorization and simplification, as well as estimation techniques, we can calculate or approximate the square root of 85. Knowing how to use square roots in real-world situations can also help us appreciate the importance of this mathematical concept.
