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 989.
The square of a number is the product of the number itself. The square of 989 is 989 × 989. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in math as 989², where 989 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 989 is 989 × 989 = 978121.
Square of 989 in exponential form: 989²
Square of 989 in arithmetic form: 989 × 989
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 989.
Step 1: Identify the number. Here, the number is 989.
Step 2: Multiplying the number by itself, we get, 989 × 989 = 978121.
The square of 989 is 978121.
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 989.
So: 989² = 989 × 989 = 978121
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 989.
Step 1: Enter the number in the calculator Enter 989 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 989 × 989
Step 3: Press the equal to button to find the answer Here, the square of 989 is 978121.
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 978121 cm².
The area of a square = a²
So, the area of a square = 978121 cm²
So, the length = √978121 = 989.
The length of each side = 989 cm
The length of a square is 989 cm. Because the area is 978121 cm², the length is √978121 = 989.
Sarah is planning to paint her square wall of length 989 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 = 989 feet
The cost to paint 1 square foot of 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 = 989
Therefore, the area of the wall = 989² = 989 × 989 = 978121.
The cost to paint the wall = 978121 × 3 = 2934363.
The total cost = 2934363 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 2934363 dollars.
Find the area of a circle whose radius is 989 meters.
The area of the circle = 3077925.86 m²
The area of a circle = πr²
Here, r = 989
Therefore, the area of the circle = π × 989²
= 3.14 × 989 × 989
= 3077925.86 m².
The area of the square is 1396 cm². Find the perimeter of the square.
The perimeter of the square is 148 cm.
The area of the square = a²
Here, the area is 1396 cm²
The length of the side is √1396 = 37
Perimeter of the square = 4a
Here, a = 37
Therefore, the perimeter = 4 × 37 = 148.
Find the square of 990.
The square of 990 is 980100.
The square of 990 is multiplying 990 by 990. So, the square = 990 × 990 = 980100
