The Concept of Square Root
Before diving into the topic of square root of 42, it is important to understand the concept of square root. Simply put, square root is a mathematical operation that determines a number which when multiplied by itself gives the original number as a product. For instance, the square root of 9 is 3 because 3 multiplied by 3 equals 9.
It is represented by the symbol √ and is widely used in various branches of mathematics, including algebra, geometry, and calculus. The square root is an essential concept in mathematics and has numerous real-life applications in fields such as science, engineering, and finance.
Finding the Square Root of 42
Now let's focus on finding the square root of 42. Unfortunately, unlike some other numbers, 42 is not a perfect square, which means that its square root cannot be expressed as a whole number or a simple fraction. In other words, it is an irrational number.
However, we can still find an approximate value of the square root of 42 through various methods, such as long division, estimation, or using a calculator. One way to do this is by using the long division method.
The Long Division Method
To use the long division method, we start by grouping the digits of the number in pairs, starting from the right-hand side. We then find the largest perfect square less than or equal to the first pair of digits and subtract it from the pair. This gives us the remainder, which we bring down the next pair of digits and repeat the process until we reach the end.
For example, to find the square root of 42 using the long division method, we start by grouping the digits into pairs: 4 and 2. We then find the largest perfect square less than or equal to 4, which is 4 itself. We subtract 4 from 4, which gives us a remainder of 0. We then bring down the next pair of digits, which is 2.
Now we have 20, and we need to find a number that when multiplied by itself gives a product less than or equal to 20. This number is 4, as 4 multiplied by 4 is 16, which is less than 20. We subtract 16 from 20, which gives us a remainder of 4. We then bring down the next pair of digits, which is 00.
We repeat the process with 400, finding the largest perfect square less than or equal to it, which is 16, and subtracting it from 400. This gives us a remainder of 336. We bring down the next pair of digits, which is 00, and add a decimal point to the quotient. We then double the quotient and find the largest digit that can be multiplied by it such that the product is less than or equal to the remainder. This digit is 5, as 25 multiplied by 13 is 325, which is less than 336.
We repeat the process with the remaining digits and obtain a value of approximately 6.4807 as the square root of 42.
Using a Calculator
Of course, using the long division method can be time-consuming and prone to errors. A more convenient and accurate way to find the square root of 42 is by using a calculator. Most scientific calculators have a square root function that can calculate the square root of any number, including irrational numbers like 42.
All you need to do is enter the number 42, press the square root button, and the calculator will give you an approximate value of the square root. In this case, the square root of 42 is approximately 6.4807, which is the same as the value obtained through the long division method.
Real-Life Applications
You may be wondering why finding the square root of 42 is important or relevant to your life. The truth is, the concept of square root has many real-life applications that we encounter daily, whether we realize it or not.
For example, in geometry, the square root is used to calculate the lengths of the sides of a right triangle using the Pythagorean theorem.
