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 145.
The square of a number is the product of the number itself. The square of 145 is 145 × 145. The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 145², where 145 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 145 is 145 × 145 = 21,025. Square of 145 in exponential form: 145² Square of 145 in arithmetic form: 145 × 145
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 145.
Step 1: Identify the number. Here, the number is 145.
Step 2: Multiplying the number by itself, we get, 145 × 145 = 21,025. The square of 145 is 21,025.
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 145. So: 145² = 145 × 145 = 21,025
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 145.
Step 1: Enter the number in the calculator Enter 145 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 145 × 145.
Step 3: Press the equal to button to find the answer Here, the square of 145 is 21,025.
Tips and Tricks for the Square of 145 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.
Find the side length of a square field, where the area of the square is 21,025 m².
The area of a square = a² So, the area of a square = 21,025 m² So, the side length = √21,025 = 145. The side length of the field = 145 m
The side length of a square field is 145 m.
Because the area is 21,025 m², the side length is √21,025 = 145.
Sarah wants to carpet her square living room, which has a side length of 145 feet. The cost to carpet a square foot is 5 dollars. How much will it cost to carpet the entire room?
The side length of the room = 145 feet The cost to carpet 1 square foot of the room = 5 dollars. To find the total cost to carpet, we find the area of the room, Area of the room = area of the square = a² Here a = 145 Therefore, the area of the room = 145² = 145 × 145 = 21,025. The cost to carpet the room = 21,025 × 5 = 105,125. The total cost = 105,125 dollars
To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per foot.
So, the total cost is 105,125 dollars.
Find the area of a circle whose radius is 145 meters.
The area of the circle = 66,132.25 m²
The area of a circle = πr²
Here, r = 145
Therefore, the area of the circle = π × 145²
= 3.14 × 145 × 145
= 66,132.25 m².
The area of the square is 21,025 cm². Find the perimeter of the square.
The perimeter of the square is 580 cm.
The area of the square = a²
Here, the area is 21,025 cm²
The length of the side is √21,025 = 145
Perimeter of the square = 4a
Here, a = 145
Therefore, the perimeter = 4 × 145 = 580 cm.
Find the square of 146.
The square of 146 is 21,316.
The square of 146 is multiplying 146 by 146.
So, the square = 146 × 146 = 21,316.
