Introduction
As humans, we are always curious about the world around us. We ask questions and seek answers to satisfy our curiosity. In mathematics, one of the most common questions is What is the square root of 90? The answer may seem simple, but there is more to it than meets the eye. In this article, we will explore the concept of the square root and how it applies to the number 90.What Is a Square Root?
A square root is a mathematical operation that determines the value that, when multiplied by itself, gives a certain number. For example, the square root of 25 is 5 because 5 multiplied by itself equals 25. In other words, a square root is the opposite of squaring a number. The symbol for the square root is √.How to Find the Square Root of 90
To find the square root of 90, we can use a calculator or do it by hand. One method is to use long division. First, we pair the digits of 90 starting from the right: 9 and 0. Then, we find the largest perfect square less than or equal to 90, which is 81 (9 x 9). We divide 90 by 81 and get 1 with a remainder of 9. We bring down the next pair of digits, which is 00. We double the quotient (2) and get 4. We then place a digit in the quotient such that the product of the divisor (162) and the quotient (24) is less than or equal to the dividend (900). We get 16 as the next digit in the quotient. We subtract the product of the divisor and the quotient from the dividend and get a remainder of 36. We bring down the next pair of digits, which is 00. We double the quotient (241) and get 482. We then place a digit in the quotient such that the product of the divisor (1624) and the quotient (241) is less than or equal to the dividend (3600). We get 2 as the next digit in the quotient. We subtract the product of the divisor and the quotient from the dividend and get a remainder of 552. We can continue this process to find more decimal places if needed.The Approximate Value of the Square Root of 90
The square root of 90 is an irrational number, which means it cannot be expressed as a finite decimal or a fraction. Its decimal representation goes on forever without repeating. However, we can approximate the value of the square root of 90 using a calculator or a table of square roots. The square root of 90 is approximately 9.48683298, rounded to eight decimal places.The Properties of Square Roots
Square roots have some interesting properties that make them useful in mathematics. One property is that the square root of a product is equal to the product of the square roots. In other words, √(ab) = √a x √b. For example, the square root of 36 times 25 is equal to the square root of 36 times the square root of 25, which is 6 x 5 = 30. Another property is that the square root of a quotient is equal to the quotient of the square roots. In other words, √(a/b) = √a / √b. For example, the square root of 144 divided by 9 is equal to the square root of 144 divided by the square root of 9, which is 12/3 = 4.The Applications of Square Roots
Square roots have many applications in science, engineering, and technology. For example, they are used in calculating distances, areas, volumes, and forces in physics and astronomy. They are also used in solving quadratic equations in algebra and in finding the roots of polynomial equations in calculus. In computer graphics, square roots are used to interpolate colors and to calculate lighting effects. In cryptography, square roots are used to encrypt and decrypt messages using public and private keys.The History of Square Roots
The concept of square roots dates back to ancient civilizations such as Egypt, Babylon, and India. The Egyptians used a method called the Horus-Eye to calculate square roots. The Babylonians used a table of square roots for practical purposes such as measuring land and building structures. The Indians developed a more sophisticated system of mathematics that included the concept of zero and the decimal system. The Greeks also studied square roots and other mathematical concepts, but they were more interested in geometry than algebra. The Arabic mathematicians preserved and expanded upon the knowledge of the ancient civilizations and transmitted it to Europe during the Middle Ages.The Symbolism of Square Roots
The symbol for the square root, √, was first used by the German mathematician Christoph Rudolff in the 16th century. It is derived from the Latin word radix, which means root. The horizontal line in the symbol represents the vinculum, which is used to indicate the extent of the operation. The number or expression under the vinculum is called the radicand. If there is no number or expression under the vinculum, it is assumed to be 2, which means the square root. The symbol for the cube root is ∛, and the symbol for the fourth root is ∜.Conclusion
In conclusion, the square root of 90 is a fascinating and important concept in mathematics. It has practical applications in many fields and has a rich history and symbolism.
