Simplifying the Square Root of 68: A Comprehensive Guide
What is the Square Root of 68 Simplified? Learn how to simplify the square root of 68 and get the exact value with our step-by-step guide!
Have you ever been tasked with finding the square root of 68? It may seem like a daunting task, but fear not! In this article, we will simplify the process and help you find the answer you seek.
To begin, let's review what a square root is. A square root is the number that, when multiplied by itself, gives us the original number. So, in the case of finding the square root of 68, we are looking for the number that, when multiplied by itself, equals 68.
Before we dive into the calculations, it's important to note that 68 is not a perfect square. This means that the answer to the square root of 68 will not be a whole number. Instead, it will be an irrational number that goes on infinitely without repeating.
So, how do we go about finding the square root of a non-perfect square? One method is to use long division. We start by grouping the digits of 68 into pairs, starting from the right. In this case, we have 6 and 8.
Next, we find the largest perfect square that is less than or equal to 68. In this case, that number is 64 (8 x 8). We then place the square root of 64, which is 8, as our first digit in the answer.
We subtract 64 from 68, which gives us 4. We bring down the next pair of digits, which is 00. We then double the 8 and get 16. We add a digit to the end of 16 to make it a two-digit number that is less than or equal to 400. We can choose any digit, but we'll choose 4 because 164 x 4 is less than 6800.
We then place 4 as our next digit in the answer, making it 84 so far. We subtract 6561 from 6800, which gives us 239. We bring down the next pair of digits, which is 00. We double 84 to get 168.
Next, we subtract the largest possible multiple of the square of the number we have so far (84 x 84) from 23900. We can see that 23900 - 7056 = 16844. We bring down the next two zeros and double the current digits to get 168.
We then repeat the process until we have as many digits as we need. After several more steps, we get an answer of approximately 8.24621125.
While this may seem like a complicated process, there are easier ways to find the square root of non-perfect squares. One method is to use a calculator or computer program. Another method is to use estimation and approximation techniques.
For example, we can estimate the square root of 68 by finding the perfect squares that are closest to 68. We know that 64 is too small and 81 is too big, so we can try 72. The square of 72 is 5184, which is greater than 68, but not by much. We can then use a technique called linear interpolation to find a more accurate estimate.
In conclusion, finding the square root of 68 may seem like a difficult task at first, but with some simple techniques, we can simplify the process and find an accurate answer. Whether we use long division, a calculator, or estimation techniques, we can rest assured that the answer we find is the right one.
The Concept of Square Roots
Before diving into the simplified form of the square root of 68, it's essential to understand the concept of square roots. In mathematics, a square root is a value that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3 because 3 x 3 = 9. Square roots are represented by a symbol known as the radical sign (√). The number inside the radical sign is called the radicand.
The Calculation of Square Roots
Calculating square roots can be done manually or using a calculator. To calculate the square root of 68 manually, we need to find the factors of 68, which are 1, 2, 4, 17, 34, and 68. Next, we group them in pairs - 1 and 68, 2 and 34, and 4. Since there are no perfect squares in the pairs, we cannot simplify them further. Therefore, the simplified form of the square root of 68 can be written as √68.
Simplifying the Square Root of 68
To simplify the square root of 68, we need to find the factors of 68 that are perfect squares. The perfect square factors of 68 are 4 and 16. We can write 68 as 4 x 17 or 16 x 4. Since 4 is a perfect square, we can write the square root of 68 as the product of the square root of 4 and the square root of 17. Therefore, the simplified form of the square root of 68 is 2√17.
The Application of Square Roots
Square roots have numerous applications in real life, particularly in geometry, physics, and engineering. They are used to calculate distances, areas, volumes, and angles. For example, in physics, the distance traveled by an object during a specific time interval can be calculated using the formula d = vt, where d is the distance, v is the velocity, and t is the time. To find the velocity, we can use the formula v = √(2gh), where g is the acceleration due to gravity, and h is the height of the object.
The Importance of Simplifying Square Roots
Simplifying square roots is essential to make mathematical calculations easier and more manageable. It also helps to identify patterns and relationships between numbers. For instance, simplifying the square root of 68 to 2√17 allows us to compare it with other numbers that have a square root of 2 or 17. This simplification can also help to solve equations and simplify expressions that involve square roots.
Other Examples of Simplified Square Roots
Here are some other examples of simplified square roots:
- √20 = 2√5
- √45 = 3√5
- √72 = 6√2
- √125 = 5√5
Using Approximations to Simplify Square Roots
In some cases, it's not possible to simplify square roots using perfect squares. In such instances, we can use approximations to simplify them. For example, to simplify the square root of 7, we can use the approximation method as follows:
- Find the two perfect squares that are closest to 7: 2² = 4 and 3² = 9
- Since 7 is closer to 4, we can use the approximation √7 ≈ √4 = 2√(7/4)
- Simplifying further, we get √7 ≈ 2√1.75
Conclusion
In conclusion, the square root of 68 can be simplified as 2√17. Simplifying square roots is essential in mathematics and has numerous applications in real life. It allows us to make calculations easier and identify patterns and relationships between numbers. Using approximations is also a handy tool for simplifying square roots that cannot be simplified using perfect squares.
