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 398.
The square of a number is the product of the number itself.
The square of 398 is 398 × 398.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 398², where 398 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 398 is 398 × 398 = 158,404.
Square of 398 in exponential form: 398²
Square of 398 in arithmetic form: 398 × 398
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 398
Step 1: Identify the number. Here, the number is 398
Step 2: Multiplying the number by itself, we get, 398 × 398 = 158,404.
The square of 398 is 158,404.
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 398
So: 398² = 398 × 398 = 158,404
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 398.
Step 1: Enter the number in the calculator Enter 398 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 398 × 398
Step 3: Press the equal to button to find the answer
Here, the square of 398 is 158,404.
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 158,404 cm².
The area of a square = a² So, the area of a square = 158,404 cm² So, the length = √158,404 = 398. The length of each side = 398 cm
The length of a square is 398 cm.
Because the area is 158,404 cm² the length is √158,404 = 398.
Sarah wants to cover her square garden of length 398 feet with tiles. Each tile costs 5 dollars. How much will she spend on tiles for the entire garden?
The length of the garden = 398 feet The cost to cover 1 square foot of the garden = 5 dollars. To find the total cost to cover the garden, we find the area of the garden, Area of the garden = area of the square = a² Here a = 398 Therefore, the area of the garden = 398² = 398 × 398 = 158,404. The cost to cover the garden = 158,404 × 5 = 792,020. The total cost = 792,020 dollars
To find the cost to cover the garden, we multiply the area of the garden by the cost to cover per foot.
So, the total cost is 792,020 dollars.
Find the area of a circle whose radius is 398 meters.
The area of the circle = 497,089.72 m²
The area of a circle = πr²
Here, r = 398
Therefore, the area of the circle = π × 398² = 3.14 × 398 × 398 = 497,089.72 m².
The area of the square is 158,404 cm². Find the perimeter of the square.
The perimeter of the square is 1,592 cm
The area of the square = a²
Here, the area is 158,404 cm²
The length of the side is √158,404 = 398
Perimeter of the square = 4a
Here, a = 398
Therefore, the perimeter = 4 × 398 = 1,592.
Find the square of 399.
The square of 399 is 159,201
The square of 399 is multiplying 399 by 399.
So, the square = 399 × 399 = 159,201
