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 this topic, we will discuss the square of 9999.
The square of a number is the product of the number itself.
The square of 9999 is 9999 × 9999.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 9999², where 9999 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 9999 is 9999 × 9999 = 99980001.
Square of 9999 in exponential form: 9999²
Square of 9999 in arithmetic form: 9999 × 9999
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 9999.
Step 1: Identify the number. Here, the number is 9999.
Step 2: Multiplying the number by itself, we get, 9999 × 9999 = 99980001.
The square of 9999 is 99980001.
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 9999
So: 9999² = 9999 × 9999 = 99980001

Step 2: Multiply the number by itself using the multiplication button (×) That is 9999 × 9999
Step 3: Press the equal to button to find the answer
Here, the square of 9999 is 99980001.
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 99980001 cm².
The area of a square = a² So, the area of a square = 99980001 cm² So, the length = √99980001 = 9999. The length of each side = 9999 cm
The length of a square is 9999 cm.
Because the area is 99980001 cm², the length is √99980001 = 9999.
Lisa is planning to tile her square floor of length 9999 feet. The cost to tile a square foot is 2 dollars. Then how much will it cost to tile the full floor?
The length of the floor = 9999 feet The cost to tile 1 square foot 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 = 9999 Therefore, the area of the floor = 9999² = 9999 × 9999 = 99980001. The cost to tile the floor = 99980001 × 2 = 199960002. The total cost = 199960002 dollars
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot.
So, the total cost is 199960002 dollars.
Find the area of a circle whose radius is 9999 meters.
The area of the circle = 314117238.86 m²
The area of a circle = πr²
Here, r = 9999
Therefore, the area of the circle = π × 9999² = 3.14 × 9999 × 9999 = 314117238.86 m².
The area of the square is 99980001 cm². Find the perimeter of the square.
The perimeter of the square is 39996 cm
The area of the square = a²
Here, the area is 99980001 cm²
The length of the side is √99980001 = 9999
Perimeter of the square = 4a
Here, a = 9999
Therefore, the perimeter = 4 × 9999 = 39996.
Find the square of 10000.
The square of 10000 is 100000000
The square of 10000 is multiplying 10000 by 10000.
So, the square = 10000 × 10000 = 100000000
