Square of -6
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 -6.
What is the Square of -6
The square of a number is the product of the number itself. The square of -6 is -6 × -6. The square of a number always ends in 0, 1, 4, 5, 6, or 9. We write it in math as (-6)², where -6 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 -6 is -6 × -6 = 36.
Square of -6 in exponential form: (-6)²
Square of -6 in arithmetic form: -6 × -6
How to Calculate the Value of Square of -6
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.
- By Multiplication Method
- Using a Formula
- Using a Calculator
By the Multiplication method
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 -6
Step 1: Identify the number. Here, the number is -6
Step 2: Multiplying the number by itself, we get, -6 × -6 = 36. The square of -6 is 36.
Using a Formula (a²)
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 -6 So: (-6)² = -6 × -6 = 36
By Using a Calculator
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 -6.
Step 1: Enter the number in the calculator Enter -6 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×) That is -6 × -6
Step 3: Press the equal to button to find the answer Here, the square of -6 is 36.
Tips and Tricks for the Square of -6: 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, √36 = 6.
Common Mistakes to Avoid When Calculating the Square of -6
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.
Mistake 1
Calculation errors:
Calculation errors mostly happen when students skip the steps or else by swapping the digits. To avoid it, students should double-check the answer. They can double-check by finding the square root of the solution they found. For example, the square of 5 is 25, and the square root of 25 is ±5.
Solved Examples on Square of -6
Problem 1
Find the length of the side of a square where the area of the square is 36 cm².
The area of a square = a²
So, the area of a square = 36 cm²
So, the length = √36 = 6.
The length of each side = 6 cm
Explanation
The length of a square is 6 cm. Because the area is 36 cm², the length is √36 = 6.
Problem 2
Anna wants to put a square rug in her room that measures -6 feet on each side. If the cost of the rug is $5 per square foot, how much will the rug cost in total?
The length of the side of the rug = -6 feet
The cost to cover 1 square foot of the rug = $5.
To find the total cost, we find the area of the rug,
Area of the rug = area of the square = a²
Here a = -6
Therefore, the area of the rug = (-6)² = -6 × -6 = 36.
The cost of the rug = 36 × 5 = 180.
The total cost = $180
Explanation
To find the cost of the rug, we multiply the area of the rug by the cost per square foot. So, the total cost is $180.
Problem 3
Find the area of a circle whose radius is -6 meters.
The area of the circle = 113.04 m²
Explanation
The area of a circle = πr²
Here, r = -6
Therefore, the area of the circle = π × (-6)² = 3.14 × -6 × -6 = 113.04 m².
Problem 4
The area of a square is 36 cm². Find the perimeter of the square.
The perimeter of the square is 24 cm.
Explanation
The area of the square = a²
Here, the area is 36 cm²
The length of the side is √36 = 6
Perimeter of the square = 4a
Here, a = 6
Therefore, the perimeter = 4 × 6 = 24 cm.
Problem 5
Find the square of -7.
The square of -7 is 49.
Explanation
The square of -7 is multiplying -7 by -7. So, the square = -7 × -7 = 49.
