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 389.
The square of a number is the product of the number itself. The square of 389 is 389 × 389.
The square of a number always ends in 0, 1, 4, 5, 6, or 9.
We write it in math as 389², where 389 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 389 is 389 × 389 = 151,321.
Square of 389 in exponential form: 389²
Square of 389 in arithmetic form: 389 × 389
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 389.
Step 1: Identify the number. Here, the number is 389.
Step 2: Multiplying the number by itself, we get, 389 × 389 = 151,321.
The square of 389 is 151,321.
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 389.
So: 389² = 389 × 389 = 151,321.
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 389.
Step 1: Enter the number in the calculator Enter 389 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 389 × 389.
Step 3: Press the equal to button to find the answer
Here, the square of 389 is 151,321.

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 151,321 cm².
The area of a square = a² So, the area of a square = 151,321 cm² So, the length = √151,321 = 389. The length of each side = 389 cm
The length of a square is 389 cm.
Because the area is 151,321 cm² the length is √151,321 = 389.
Alice is planning to paint her square wall of length 389 feet. The cost to paint a foot is 5 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 389 feet The cost to paint 1 square foot of wall = is 5 dollars. To find the total cost to paint, we find the area of the wall, Area of the wall = area of the square = a² Here a = 389 Therefore, the area of the wall = 389² = 389 × 389 = 151,321. The cost to paint the wall = 151,321 × 5 = 756,605. The total cost = 756,605 dollars
To find the cost to paint the wall, we multiply the area of the wall by cost to paint per foot.
So, the total cost is 756,605 dollars.
Find the area of a circle whose radius is 389 meters.
The area of the circle = 475,291.18 m²
The area of a circle = πr²
Here, r = 389
Therefore, the area of the circle = π × 389² = 3.14 × 389 × 389 = 475,291.18 m².
The area of the square is 151,321 cm². Find the perimeter of the square.
The perimeter of the square is 1,556 cm.
The area of the square = a²
Here, the area is 151,321 cm²
The length of the side is √151,321 = 389
Perimeter of the square = 4a
Here, a = 389
Therefore, the perimeter = 4 × 389 = 1,556.
Find the square of 390.
The square of 390 is 152,100
The square of 390 is multiplying 390 by 390.
So, the square = 390 × 390 = 152,100
