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 79.
What is the Square of 79
The square of a number is the product of the number itself. The square of 79 is 79 × 79. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in math as 79², where 79 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 79 is 79 × 79 = 6241. Square of 79 in exponential form: 79² Square of 79 in arithmetic form: 79 × 79
How to Calculate the Value of Square of 79
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
By the Multiplication Method
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 79 Step 1: Identify the number. Here, the number is 79 Step 2: Multiplying the number by itself, we get, 79 × 79 = 6241. The square of 79 is 6241.
Using a Formula (a²)
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 79 So: 79² = 79 × 79 = 6241
By Using a Calculator
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 79. Step 1: Enter the number in the calculator Enter 79 in the calculator. Step 2: Multiply the number by itself using the multiplication button (×) That is 79 × 79 Step 3: Press the equal to button to find the answer Here, the square of 79 is 6241. Tips and Tricks for the Square of 79 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.
Common Mistakes to Avoid When Calculating the Square of 79
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.
Mistake 1
Calculation errors:
Calculation errors mostly happen when students skip the steps or swap the digits. To avoid it, students should double-check the answer. They can double-check by finding the square root of the solution they found. For example, the square of 25 is 625, and the square root of 625 is ±25.
Mistake 2
Errors when using the formula.
The formula to find the square of the number is a². Instead, students may use 79² with (7 +9)² or (70 + 9)². So students should check and use the correct formula and double-check the answers to avoid all the confusion.
Mistake 3
Confusing with square and square root.
Not understanding the concept of square and square root can lead to confusion in students. To avoid it, students should understand the concept that square and square root are inverse operations. The square of 5 is 25, and the square root of 25 is ±5.
Mistake 4
Errors in parentheses.
Ignoring the parentheses when finding the square of a number can lead to errors. So, students should understand parentheses. And do the operations in the correct order to avoid error.
Mistake 5
Not practicing regularly.
Regular practice is required to master the square of a number. So students should do regular practice to avoid errors.
Solved Examples on Square of 79
Problem 1
Find the edge length of a cube, where the surface area of the cube is 6241 cm².
The surface area of a cube = 6a² So, the surface area of a cube = 6241 cm² So, the edge length = √(6241/6) ≈ 79. The edge length of the cube is approximately 79 cm.
Explanation
The edge length of the cube is approximately 79 cm. Because the surface area is 6241 cm², we find the edge length as √(6241/6) ≈ 79.
Problem 2
Sarah is designing a square garden plot with a side length of 79 meters. Each square meter costs $5 to landscape. What is the total cost to landscape the entire plot?
The side length of the garden plot = 79 meters The cost to landscape 1 square meter = $5 To find the total cost, calculate the area of the plot, Area of the plot = side² Here, side = 79 Therefore, the area of the plot = 79² = 79 × 79 = 6241. The cost to landscape the plot = 6241 × 5 = $31,205. The total cost = $31,205
Explanation
To find the cost to landscape the plot, we multiply the area of the plot by the cost per square meter. So, the total cost is $31,205.
Problem 3
Find the area of a circle whose diameter is 79 meters.
The area of the circle = 4909.24 m²
Explanation
The area of a circle = πr² Here, diameter = 79, so radius r = 79/2 = 39.5 Therefore, the area of the circle = π × (39.5)² = 3.14 × 39.5 × 39.5 ≈ 4909.24 m².
Problem 4
The area of a square is 6241 cm². Find the perimeter of the square.
The perimeter of the square is 316 cm.
Explanation
The area of the square = a² Here, the area is 6241 cm² The length of the side is √6241 = 79 Perimeter of the square = 4a Here, a = 79 Therefore, the perimeter = 4 × 79 = 316 cm.
Problem 5
Find the square of 80.
The square of 80 is 6400.
Explanation
The square of 80 is multiplying 80 by 80. So, the square = 80 × 80 = 6400.
