Square of 730
The product of multiplying an integer by itself is the square of a number. Squares are used in programming, calculating areas, and so on. In this topic, we will discuss the square of 730.
What is the Square of 730
The square of a number is the product of the number itself. The square of 730 is 730 × 730. The square of a number can end in various digits depending on the number. We write it in math as 730², where 730 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 730 is 730 × 730 = 532,900. Square of 730 in exponential form: 730² Square of 730 in arithmetic form: 730 × 730
How to Calculate the Value of Square of 730
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 730. Step 1: Identify the number. Here, the number is 730. Step 2: Multiplying the number by itself, we get, 730 × 730 = 532,900. The square of 730 is 532,900.
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 730. So: 730² = 730 × 730 = 532,900
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 730. Step 1: Enter the number in the calculator Enter 730 in the calculator. Step 2: Multiply the number by itself using the multiplication button (×) That is 730 × 730 Step 3: Press the equal to button to find the answer Here, the square of 730 is 532,900. Tips and Tricks for the Square of 730 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 related to the last digit of the base number. 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 730
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 else by swapping 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 will be using the formula.
The formula to find the square of the number is a². Instead, students may use 730² with (7 + 30)² or (700 + 30)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 perform the operations in the correct order to avoid errors.
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 730
Problem 1
Find the length of a square, where the area of the square is 532,900 cm².
The area of a square = a² So, the area of a square = 532,900 cm² So, the length = √532,900 = 730. The length of each side = 730 cm
Explanation
The length of a square is 730 cm. Because the area is 532,900 cm², the length is √532,900 = 730.
Problem 2
Lisa is planning to tile her square garden, which has a length of 730 feet. The cost to tile a square foot is 5 dollars. Then how much will it cost to tile the full garden?
The length of the garden = 730 feet The cost to tile 1 square foot of garden = 5 dollars. To find the total cost to tile, we find the area of the garden, Area of the garden = area of the square = a² Here a = 730 Therefore, the area of the garden = 730² = 730 × 730 = 532,900. The cost to tile the garden = 532,900 × 5 = 2,664,500. The total cost = 2,664,500 dollars
Explanation
To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per foot. So, the total cost is 2,664,500 dollars.
Problem 3
Find the area of a circle whose radius is 730 meters.
The area of the circle = 1,675,438.1 m²
Explanation
The area of a circle = πr² Here, r = 730 Therefore, the area of the circle = π × 730² = 3.14 × 730 × 730 = 1,675,438.1 m².
Problem 4
The area of the square is 532,900 cm². Find the perimeter of the square.
The perimeter of the square is 2,920 cm.
Explanation
The area of the square = a² Here, the area is 532,900 cm² The length of the side is √532,900 = 730 Perimeter of the square = 4a Here, a = 730 Therefore, the perimeter = 4 × 730 = 2,920.
Problem 5
Find the square of 731.
The square of 731 is 534,361.
Explanation
The square of 731 is multiplying 731 by 731. So, the square = 731 × 731 = 534,361
