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 the topic, we will discuss the square of 7921.
The square of a number is the product of the number itself.
The square of 7921 is 7921 × 7921.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 7921², where 7921 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 7921 is 7921 × 7921 = 62,726,641.
Square of 7921 in exponential form: 7921²
Square of 7921 in arithmetic form: 7921 × 7921
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.
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 7921
Step 1: Identify the number. Here, the number is 7921
Step 2: Multiplying the number by itself, we get, 7921 × 7921 = 62,726,641.
The square of 7921 is 62,726,641.
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 7921
So: 7921² = 7921 × 7921 = 62,726,641

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.
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 62,726,641 cm².
The area of a square = a² So, the area of a square = 62,726,641 cm² So, the length = √62,726,641 = 7921. The length of each side = 7921 cm
The length of a square is 7921 cm.
Because the area is 62,726,641 cm² the length is √62,726,641 = 7921.
Sarah wants to cover her square garden of length 7921 feet with tiles. If each tile covers 1 square foot and costs 5 dollars, how much will it cost to cover the whole garden?
The length of the garden = 7921 feet The cost to cover 1 square foot of garden = 5 dollars. To find the total cost to cover, we find the area of the garden, Area of the garden = area of the square = a² Here a = 7921 Therefore, the area of the garden = 7921² = 62,726,641. The cost to cover the garden = 62,726,641 × 5 = 313,633,205. The total cost = 313,633,205 dollars
To find the cost to cover the garden, we multiply the area of the garden by the cost to cover per foot.
So, the total cost is 313,633,205 dollars.
Find the area of a circle whose radius is 7921 meters.
The area of the circle = 197,920,958.04 m²
The area of a circle = πr²
Here, r = 7921
Therefore, the area of the circle = π × 7921² = 3.14 × 7921 × 7921 = 197,920,958.04 m².
The area of the square is 63,025 cm². Find the perimeter of the square.
The perimeter of the square is 1004 cm.
The area of the square = a²
Here, the area is 63,025 cm²
The length of the side is √63,025 = 251
Perimeter of the square = 4a
Here, a = 251
Therefore, the perimeter = 4 × 251 = 1004.
Find the square of 7922.
The square of 7922 is 62,742,484.
The square of 7922 is multiplying 7922 by 7922.
So, the square = 7922 × 7922 = 62,742,484.
