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 26.
The square of a number is the product of the number with itself. The square of 26 is 26 × 26. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in math as 26², where 26 is the base and 2 is the exponent. The square of a positive and a negative number is always positive.
For example, 5² = 25; (-5)² = 25.
The square of 26 is 26 × 26 = 676.
Square of 26 in exponential form: 26²
Square of 26 in arithmetic form: 26 × 26
The square of a number is obtained by multiplying the number by itself. Let's explore 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 multiply the number by itself to find the square. The product here is the square of the number. Let's find the square of 26:
Step 1: Identify the number. Here, the number is 26.
Step 2: Multiplying the number by itself, we get, 26 × 26 = 676.
The square of 26 is 676.
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 26.
So: 26² = 26 × 26 = 676
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 26.
Step 1: Enter the number in the calculator Enter 26 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is 26 × 26
Step 3: Press the equal to button to find the answer Here, the square of 26 is 676.
Tips and Tricks for the Square of 26
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 involves 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 676 cm².
The area of a square = a²
So, the area of a square = 676 cm²
Thus, the length = √676 = 26.
The length of each side = 26 cm
The length of a square is 26 cm. Because the area is 676 cm², the length is √676 = 26.
Sarah is planning to paint her square wall of length 26 feet. The cost to paint a foot is 5 dollars. How much will it cost to paint the full wall?
The length of the wall = 26 feet
The cost to paint 1 square foot of wall = 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 = 26
Therefore, the area of the wall = 26² = 26 × 26 = 676.
The cost to paint the wall = 676 × 5 = 3380.
The total cost = 3380 dollars
To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot. So, the total cost is 3380 dollars.
Find the area of a circle whose radius is 26 meters.
The area of the circle = 2123.72 m²
The area of a circle = πr²
Here, r = 26
Therefore, the area of the circle = π × 26²
= 3.14 × 26 × 26
= 2123.72 m².
The area of the square is 676 cm². Find the perimeter of the square.
The perimeter of the square is 104 cm.
The area of the square = a²
Here, the area is 676 cm²
The length of the side is √676 = 26
Perimeter of the square = 4a
Here, a = 26
Therefore, the perimeter = 4 × 26 = 104.
Find the square of 27.
The square of 27 is 729.
The square of 27 is found by multiplying 27 by 27.
So, the square = 27 × 27 = 729.
