Introduction
Mathematics is a crucial subject that plays a significant role in our daily lives. It helps us understand the world around us and solve problems efficiently. One of the fundamental concepts in mathematics is the square root. Square roots are used in various fields, from physics to engineering, to calculate measurements and values. In this article, we will explore what the square root of 86 is and how to find it.
What is a Square Root?
A square root is a number that, when multiplied by itself, gives the original number. For instance, the square root of 25 is 5 because 5 x 5 = 25. The symbol for square root is √. So, we write the square root of 25 as √25.
Finding the Square Root of 86
Now that we know what a square root is let's find the square root of 86. To do so, we need to use a calculator or manual methods. Since the square root of 86 is not a perfect square, we cannot find it through simple multiplication. Therefore, we need to use other methods to find its value.
Method 1 - Long Division
One way to find the square root of a number is through long division. Here's how it works:
- Divide the number into pairs of digits from the right.
- Find the largest number whose square is less than or equal to the first pair.
- Write down the quotient and subtract the product from the first pair.
- Bring down the next pair and double the quotient.
- Find the largest number whose product with the quotient is less than or equal to the remaining digits.
- Repeat steps 3-5 until all the pairs are used up.
Using this method, we can find that the square root of 86 is approximately 9.2736.
Method 2 - Estimation
Another way to find the square root of a number is through estimation. This method is quicker but not as accurate as long division. Here's how it works:
- Find the two perfect squares that surround the number.
- Estimate the value of the square root based on how close the number is to the perfect squares.
Using this method, we can estimate that the square root of 86 is between 9 and 10.
Uses of Square Roots
Square roots have numerous applications in various fields, including:
- Engineering - to calculate the length of cables, wires, and pipes.
- Physics - to calculate velocity, acceleration, and other physical quantities.
