The Concept of Square Root: A Brief Introduction
Square root is a mathematical concept that involves finding the number that, when multiplied by itself, gives a particular number. For instance, the square root of 16 is 4 because 4 x 4 = 16. Similarly, the square root of 25 is 5 as 5 x 5 = 25. The symbol for square root is √.
In this article, we will delve into the world of square root and focus on the square root of 45. We will explore the various ways to calculate the square root of 45 and understand its significance in mathematics.
The Importance of Square Root in Mathematics
Square root is a crucial concept in mathematics as it is used in various fields such as physics, engineering, and finance. It helps us in finding the roots of quadratic equations, calculating distances, determining areas, and much more.
It is also a fundamental concept in geometry, where it is used to find the length of the sides of a triangle. In addition, square roots play a vital role in calculus, where they are used to calculate derivatives and integrals.
Calculating the Square Root of 45 Using Prime Factorization Method
One way to calculate the square root of 45 is by prime factorization method. Firstly, we need to find the prime factors of 45, which are 3 and 5. Then, we group the prime factors in pairs of two and take one number from each pair. In this case, we have only one pair, which is (3 x 3) and (5). So, we take one 3 and one 5.
Next, we multiply the two numbers: 3 x 5 = 15. This gives us the square root of 45 as 3√5.
Calculating the Square Root of 45 Using Long Division Method
Another way to calculate the square root of 45 is by the long division method. Firstly, we divide 45 by 4 and get 11 as the quotient with a remainder of 1. Next, we bring down the next two digits (00) and place it next to the remainder.
We double the quotient (11) and get 22. We then find the largest number that can be multiplied by 22 and still be less than or equal to 100. In this case, it is 9. We write 9 as the next digit of the quotient and subtract 81 from 100, which gives us a remainder of 19.
We bring down the next two digits (00) and place it next to the remainder. We double the quotient (119) and repeat the process. We find the largest number that can be multiplied by 238 and still be less than or equal to 1900. In this case, it is 7. We write 7 as the next digit of the quotient and subtract 1681 from 1900, which gives us a remainder of 219.
We repeat the process until we get the desired accuracy. In this case, we get 6.708203932499369 as the square root of 45.
The Square Root of 45 in Decimal Form

Square root is a fundamental concept in geometry, calculus, and finance, to name a few. It has several properties that make it a useful tool in solving complex mathematical problems.
Understanding the concept of square root is essential for students pursuing mathematics or related fields. It helps in developing critical thinking and problem-solving skills, which are crucial in today's world.
Understanding the Concept of Square Root
Square root is a mathematical operation used to find the value that, when multiplied by itself, gives a certain number. For example, the square root of 9 is 3, because 3 x 3 = 9. It is denoted by the symbol √. Square roots can be either rational or irrational numbers. Rational square roots are those that can be expressed as a fraction, while irrational square roots cannot. Understanding the concept of square root is essential in mathematics and many real-life applications.
The History of Square Root
The concept of square root dates back to ancient civilizations such as Babylonians and Egyptians who used it for practical purposes such as measuring land and building structures. However, it was the Greek mathematician Pythagoras who is credited with the discovery of the Pythagorean Theorem, which relates to the square of the hypotenuse of a right-angled triangle. This theorem led to the development of the concept of square root. Over time, many mathematicians such as Euclid, Archimedes, and Diophantus contributed to the understanding and calculation of square roots. Today, square roots are used extensively in various fields of mathematics and science.
Finding Square Root without Calculator
While calculators have made finding square roots easier, it is still important to know how to do it manually. One method is by long division. For example, to find the square root of 45, we start by grouping the digits into pairs from the right, starting with the units digit. In this case, we have 4 and 5. We then find the largest number whose square is less than or equal to 4, which is 2. This becomes our first digit. We subtract 4 from 45, giving us 41, and bring down the next pair of digits, giving us 415. We double our first digit (2) and get 4. We then find the largest number whose product with 4 is less than or equal to 415, which is 10. This becomes our second digit. We subtract 400 from 415, giving us 15, which becomes our new dividend. We repeat the process until we get the desired accuracy.
How to Simplify Square Roots
Simplifying square roots involves expressing them in their simplest form. For example, the square root of 72 can be simplified as follows: we first factorize 72 into its prime factors, which are 2 x 2 x 2 x 3 x 3. We then group the factors into pairs, taking out any perfect squares. In this case, we have 2 x 2 x 3 x 3 x 2, which can be simplified as 2 x 3 √2. Another method is to use the properties of exponents, which state that the square root of a product is equal to the product of the square roots of the factors. For example, the square root of 12 x 27 can be simplified as √(12 x 27) = √12 x √27 = 2√3 x 3√3 = 6√3.
Tricks to Solve Irrational Square Roots
Irrational square roots are those that cannot be expressed as a fraction and have an infinite decimal expansion. One trick to solving them is by using approximations. For example, to find the square root of 7, we can start by guessing a number that is close to it, such as 2. We then divide 7 by 2, which gives us 3.5. We take the average of 2 and 3.5, which is 2.75, and divide 7 by 2.75, giving us 2.54. We repeat the process until we get the desired accuracy. Another trick is to use the binomial theorem, which states that (a + b)² = a² + 2ab + b². For example, to find the square root of 13, we can express it as (3 + √4)(3 - √4), which simplifies to 9 - 4 = 5.
Common Misconceptions about Square Roots
One common misconception about square roots is that they always have two solutions. This is not true, as some square roots only have one solution, while others have none. Another misconception is that the square root of a negative number does not exist. While this is true for real numbers, complex numbers allow us to find the square root of negative numbers.
Applications of Square Root in Real Life
Square roots are used in various fields such as engineering, physics, architecture, and finance. They are used to calculate distances, areas, volumes, and forces. For example, the Pythagorean Theorem is used to calculate the distance between two points in a two-dimensional space, while the Law of Cosines is used to calculate distances and angles in a three-dimensional space. In finance, square roots are used to calculate interest rates and investment returns.
Advanced Square Root Topics
Advanced topics related to square roots include complex numbers, higher-degree roots, and fractional exponents. Complex numbers involve the use of imaginary numbers, which are expressed as a multiple of the square root of -1. Higher-degree roots involve the calculation of cube roots, fourth roots, and higher-order roots. Fractional exponents involve expressing square roots as fractional powers, such as √a = a^(1/2).
Square Roots in Mathematics
Square roots are used extensively in various branches of mathematics such as algebra, trigonometry, calculus, and number theory. They are used to solve equations, find roots of polynomials, calculate areas and volumes, and prove theorems. For example, the Quadratic Formula involves finding the square root of the discriminant, while the Fundamental Theorem of Algebra states that every polynomial equation has at least one complex root.
