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 6400.
The square of a number is the product of the number itself.
The square of 6400 is 6400 × 6400.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 6400², where 6400 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 6400 is 6400 × 6400 = 40,960,000.
Square of 6400 in exponential form: 6400²
Square of 6400 in arithmetic form: 6400 × 6400
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 6400.
Step 1: Identify the number. Here, the number is 6400.
Step 2: Multiplying the number by itself, we get, 6400 × 6400 = 40,960,000.
The square of 6400 is 40,960,000.
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 6400
So: 6400² = 6400 × 6400 = 40,960,000
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 6400.
Step 1: Enter the number in the calculator Enter 6400 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 6400 × 6400
Step 3: Press the equal to button to find the answer
Here, the square of 6400 is 40,960,000.
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 40,960,000 cm².
The area of a square = a² So, the area of a square = 40,960,000 cm² So, the length = √40,960,000 = 6400. The length of each side = 6400 cm
The length of a square is 6400 cm.
Because the area is 40,960,000 cm² the length is √40,960,000 = 6400.
Sarah is planning to tile her square kitchen floor of length 6400 inches. The cost to tile a square inch is 2 dollars. Then how much will it cost to tile the full floor?
The length of the kitchen floor = 6400 inches The cost to tile 1 square inch of floor = 2 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 = 6400 Therefore, the area of the floor = 6400² = 6400 × 6400 = 40,960,000. The cost to tile the floor = 40,960,000 × 2 = 81,920,000. The total cost = 81,920,000 dollars
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per square inch.
So, the total cost is 81,920,000 dollars.
Find the area of a circle whose radius is 6400 meters.
The area of the circle = 128,679,360 m²
The area of a circle = πr²
Here, r = 6400
Therefore, the area of the circle = π × 6400² = 3.14 × 6400 × 6400 = 128,679,360 m².
The area of the square is 49,000,000 cm². Find the perimeter of the square.
The perimeter of the square is
The area of the square = a²
Here, the area is 49,000,000 cm²
The length of the side is √49,000,000 = 7000
Perimeter of the square = 4a
Here, a = 7000
Therefore, the perimeter = 4 × 7000 = 28,000.
Find the square of 6410.
The square of 6410 is 41,088,100
The square of 6410 is multiplying 6410 by 6410.
So, the square = 6410 × 6410 = 41,088,100
