The product of multiplying an integer by itself is the square of a number. Square is used in programming, calculating areas, and so on. In this topic, we will discuss the square of 82.
The square of a number is the product of the number itself. The square of 82 is 82 × 82. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in math as 82², where 82 is the base and 2 is the exponent. The square of a positive and a negative number is always positive. For example, 5² = 25; -5² = 25. The square of 82 is 82 × 82 = 6724. Square of 82 in exponential form: 82² Square of 82 in arithmetic form: 82 × 82
The square of a number is multiplying the number by itself. So let’s learn how to find the square of a number. These are the common methods used to find the square of a number. By Multiplication Method Using a Formula Using a Calculator
In this method, we will multiply the number by itself to find the square. The product here is the square of the number. Let’s find the square of 82. Step 1: Identify the number. Here, the number is 82. Step 2: Multiplying the number by itself, we get, 82 × 82 = 6724. The square of 82 is 6724.
In this method, the formula, a² is used to find the square of the number. Where a is the number. Step 1: Understanding the equation Square of a number = a² a² = a × a Step 2: Identifying the number and substituting the value in the equation. Here, ‘a’ is 82. So: 82² = 82 × 82 = 6724
Using a calculator to find the square of a number is the easiest method. Let’s learn how to use a calculator to find the square of 82. Step 1: Enter the number in the calculator Enter 82 in the calculator. Step 2: Multiply the number by itself using the multiplication button (×). That is 82 × 82. Step 3: Press the equal to button to find the answer. Here, the square of 82 is 6724. Tips and Tricks for the Square of 82 Tips and tricks make it easy for students to understand and learn the square of a number. To master the square of a number, these tips and tricks will help students. The square of an even number is always an even number. For example, 6² = 36. The square of an odd number is always an odd number. For example, 5² = 25. The last digit of the square of a number is always 0, 1, 4, 5, 6, or 9. If the square root of a number is a fraction or a decimal, then the number is not a perfect square. For example, √1.44 = 1.2. The square root of a perfect square is always a whole number. For example, √144 = 12.
Mistakes are common among kids when doing math, especially when it is finding the square of a number. Let’s learn some common mistakes to master the squaring of a number.
Find the length of the square, where the area of the square is 6724 cm².
The area of a square = a² So, the area of a square = 6724 cm² So, the length = √6724 = 82. The length of each side = 82 cm
The length of a square is 82 cm. Because the area is 6724 cm², the length is √6724 = 82.
Sarah is planning to paint her square wall of length 82 feet. The cost to paint a foot is 2 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 82 feet The cost to paint 1 square foot of wall = 2 dollars. To find the total cost to paint, we find the area of the wall, Area of the wall = area of the square = a² Here a = 82 Therefore, the area of the wall = 82² = 82 × 82 = 6724. The cost to paint the wall = 6724 × 2 = 13448. The total cost = 13448 dollars
To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot. So, the total cost is 13448 dollars.
Find the area of a circle whose radius is 82 meters.
The area of the circle = 21134.72 m²
The area of a circle = πr² Here, r = 82 Therefore, the area of the circle = π × 82² = 3.14 × 82 × 82 = 21134.72 m².
The area of the square is 6724 cm². Find the perimeter of the square.
The perimeter of the square is 328 cm.
The area of the square = a² Here, the area is 6724 cm² The length of the side is √6724 = 82 Perimeter of the square = 4a Here, a = 82 Therefore, the perimeter = 4 × 82 = 328.
Find the square of 83.
The square of 83 is 6889.
The square of 83 is multiplying 83 by 83. So, the square = 83 × 83 = 6889.
Perfect square: A number that is the square of an integer. For example, 64 is a perfect square because it is 8². Exponential form: A way of writing numbers using a base and an exponent. For example, 82², where 82 is the base and 2 is the exponent. Square root: The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 81 is 9. Prime number: A number greater than 1 that has no positive divisors other than 1 and itself. For example, 2, 3, 5, and 7 are prime numbers. Even number: A number divisible by 2 without a remainder. For example, 2, 4, 6, and 8 are even numbers.
