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 129.
The square of a number is the product of the number itself. The square of 129 is 129 × 129. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in math as 129², where 129 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 129 is 129 × 129 = 16641. Square of 129 in exponential form: 129² Square of 129 in arithmetic form: 129 × 129
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 129
Step 1: Identify the number. Here, the number is 129
Step 2: Multiplying the number by itself, we get, 129 × 129 = 16641. The square of 129 is 16641.
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 129 So: 129² = 129 × 129 = 16641
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 129.
Step 1: Enter the number in the calculator Enter 129 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 129 × 129
Step 3: Press the equal to button to find the answer Here, the square of 129 is 16641.
Tips and Tricks for the Square of 129 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. The square of an even number is always an even number. For example, 6² = 36 The square of an odd number is always an odd number. For example, 5² = 25 The last digit of the square of a number is always 0, 1, 4, 5, 6, or 9. If the square root of a number is a fraction or a decimal, then the number is not a perfect square. For example, √1.44 = 1.2 The square root of a perfect square is always a whole number. For example, √144 = 12.
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.
A square park has an area of 16641 m². What is the length of each side of the park?
The area of a square = a² So, the area of a square = 16641 m² So, the length = √16641 = 129. The length of each side = 129 m
The length of a square park is 129 m.
Because the area is 16641 m², the length is √16641 = 129.
Sam is tiling a square floor that is 129 feet long on each side. If each tile costs 2 dollars, how much will it cost to tile the entire floor?
The length of the floor = 129 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 = 129 Therefore, the area of the floor = 129² = 129 × 129 = 16641. The cost to tile the floor = 16641 × 2 = 33282. The total cost = 33282 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 33282 dollars.
Find the area of a circle whose radius is 129 meters.
The area of the circle = 52281.48 m²
The area of a circle = πr²
Here, r = 129
Therefore, the area of the circle = π × 129²
= 3.14 × 129 × 129
= 52281.48 m².
The area of a square is 16641 m². Find the perimeter of the square.
The perimeter of the square is 516 m.
The area of the square = a²
Here, the area is 16641 m²
The length of the side is √16641 = 129
Perimeter of the square = 4a
Here, a = 129
Therefore, the perimeter = 4 × 129 = 516.
Find the square of 130.
The square of 130 is 16900
The square of 130 is multiplying 130 by 130.
So, the square = 130 × 130 = 16900
