The product of multiplying an integer by itself is the square of a number. Square is used in programming, calculating areas, and more. In this topic, we will discuss the square of 1989.
The square of a number is the product of the number itself.
The square of 1989 is 1989 × 1989.
The square of a number can end in 0, 1, 4, 5, 6, or 9.
We write it in math as 1989², where 1989 is the base and 2 is the exponent.
The square of both positive and negative numbers is always positive. For example, 5² = 25; (-5)² = 25.
The square of 1989 is 1989 × 1989 = 3,956,721.
Square of 1989 in exponential form: 1989²
Square of 1989 in arithmetic form: 1989 × 1989
The square of a number is determined by multiplying the number by itself. Here are common methods used to find the square of a number:
In this method, we multiply the number by itself to find the square. The product is the square of the number. Let’s find the square of 1989.
Step 1: Identify the number. Here, the number is 1989.
Step 2: Multiplying the number by itself, we get, 1989 × 1989 = 3,956,721.
The square of 1989 is 3,956,721.
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 1989. So: 1989² = 1989 × 1989 = 3,956,721
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 1989.
Step 1: Enter the number in the calculator. Enter 1989 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 1989 × 1989.
Step 3: Press the equal to button to find the answer. Here, the square of 1989 is 3,956,721.
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 comes to 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 3,956,721 cm².
The area of a square = a²
So, the area of a square = 3,956,721 cm²
So, the length = √3,956,721 = 1989.
The length of each side = 1989 cm
The length of a square is 1989 cm because the area is 3,956,721 cm², and the length is √3,956,721 = 1989.
Sarah is planning to tile her square floor, which has a length of 1989 feet. The cost to tile one square foot is 5 dollars. How much will it cost to tile the entire floor?
The length of the floor = 1989 feet
The cost to tile 1 square foot of floor = 5 dollars.
To find the total cost to tile, we find the area of the floor,
Area of the floor = area of the square = a²
Here a = 1989
Therefore, the area of the floor = 1989² = 1989 × 1989 = 3,956,721.
The cost to tile the floor = 3,956,721 × 5 = 19,783,605.
The total cost = 19,783,605 dollars
To find the cost to tile the floor, multiply the area of the floor by the cost to tile per foot.
So, the total cost is 19,783,605 dollars.
Find the area of a circle whose radius is 1989 meters.
The area of the circle = 12,432,720.66 m²
The area of a circle = πr²
Here, r = 1989
Therefore, the area of the circle = π × 1989² = 3.14 × 1989 × 1989 = 12,432,720.66 m².
The area of the square is 3,956,721 cm². Find the perimeter of the square.
The perimeter of the square is 7,956 cm
The area of the square = a²
Here, the area is 3,956,721 cm²
The length of the side is √3,956,721 = 1989
Perimeter of the square = 4a
Here, a = 1989
Therefore, the perimeter = 4 × 1989 = 7,956.
Find the square of 1990.
The square of 1990 is 3,960,100
The square of 1990 is found by multiplying 1990 by 1990.
So, the square = 1990 × 1990 = 3,960,100.
