The product of multiplying an integer by itself is the square of a number. The square is used in programming, calculating areas, and so on. In this topic, we will discuss the square of 987.
The square of a number is the product of the number itself. The square of 987 is 987 × 987. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in math as 987², where 987 is the base and 2 is the exponent. The square of a positive and a negative number is always positive.
For example, 5² = 25; (-5)² = 25.
The square of 987 is 987 × 987 = 974169.
Square of 987 in exponential form: 987²
Square of 987 in arithmetic form: 987 × 987
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 987.
Step 1: Identify the number. Here, the number is 987.
Step 2: Multiplying the number by itself, we get, 987 × 987 = 974169.
The square of 987 is 974169.
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 987.
So: 987² = 987 × 987 = 974169
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 987.
Step 1: Enter the number in the calculator Enter 987 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 987 × 987
Step 3: Press the equal to button to find the answer Here, the square of 987 is 974169.
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 974169 cm².
The area of a square = a²
So, the area of a square = 974169 cm²
So, the length = √974169 = 987.
The length of each side = 987 cm
The length of a square is 987 cm. Because the area is 974169 cm², the length is √974169 = 987.
Sara is planning to paint her square wall of length 987 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 987 feet
The cost to paint 1 square foot of the wall = 3 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 = 987
Therefore, the area of the wall = 987² = 987 × 987 = 974169.
The cost to paint the wall = 974169 × 3 = 2922507.
The total cost = 2922507 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 2922507 dollars.
Find the area of a circle whose radius is 987 meters.
The area of the circle = 3,059,436.66 m²
The area of a circle = πr²
Here, r = 987
Therefore, the area of the circle = π × 987²
= 3.14 × 987 × 987
= 3,059,436.66 m².
The area of the square is 984076 cm². Find the perimeter of the square.
The perimeter of the square is
The area of the square = a²
Here, the area is 984076 cm²
The length of the side is √984076 = 992
Perimeter of the square = 4a
Here, a = 992
Therefore, the perimeter = 4 × 992 = 3968.
Find the square of 988.
The square of 988 is 976144
The square of 988 is multiplying 988 by 988. So, the square = 988 × 988 = 976144
