Step 2: Multiply the number by itself using the multiplication button (×). That is 8100 × 8100.
Step 3: Press the equal to button to find the answer. Here, the square of 8100 is 65610000.
Tips and Tricks for the Square of 8100
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.
Common Mistakes to Avoid When Calculating the Square of 8100
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 25 is 625, and the square root of 625 is ±25.
Mistake 2
Errors will be using the formula.
The formula to find the square of the number is a². Instead, students may use 8100² with (8+1+0+0)² or (8000+100)². So students should check and use the correct formula and double-check the answers to avoid all the confusion.
Mistake 3
Confusing with square and square root.
Not understanding the concept of square and square root can lead to confusion in students. To avoid it, students should understand the concept that square and square root are inverse operations. The square of 5 is 25 and the square root of 25 is ±5.
Mistake 4
Errors in parentheses.
Ignoring the parentheses when finding the square of a number can lead to errors. So, students should understand parentheses and do the operations in the correct order to avoid error.
Mistake 5
Not practicing regularly.
Regular practice is required to master the square of a number. So students should do regular practice to avoid errors.
Solved Examples on Square of 8100
Problem 1
Find the length of the square, where the area of the square is 65610000 cm².
The area of a square = a² So, the area of a square = 65610000 cm² So, the length = √65610000 = 8100. The length of each side = 8100 cm
Explanation
The length of a square is 8100 cm.
Because the area is 65610000 cm² the length is √65610000 = 8100.
Problem 2
Sarah wants to tile her square courtyard with tiles of length 8100 feet. Each tile costs 5 dollars. How much will it cost to tile the entire courtyard?
The length of the courtyard = 8100 feet. The cost to tile 1 square foot of courtyard = 5 dollars. To find the total cost to tile, we find the area of the courtyard, Area of the courtyard = area of the square = a² Here a = 8100. Therefore, the area of the courtyard = 8100² = 8100 × 8100 = 65610000. The cost to tile the courtyard = 65610000 × 5 = 328050000. The total cost = 328050000 dollars.
Explanation
To find the cost to tile the courtyard, we multiply the area of the courtyard by the cost to tile per foot.
So, the total cost is 328050000 dollars.
Problem 3
Find the area of a circle whose radius is 8100 meters.
The area of the circle = 206158430.56 m²
Explanation
The area of a circle = πr²
Here, r = 8100
Therefore, the area of the circle = π × 8100² = 3.14 × 8100 × 8100 = 206158430.56 m².
Problem 4
The area of the square is 65610000 cm². Find the perimeter of the square.
The perimeter of the square is 32400 cm.
Explanation
The area of the square = a²
Here, the area is 65610000 cm².
The length of the side is √65610000 = 8100.
Perimeter of the square = 4a
Here, a = 8100.
Therefore, the perimeter = 4 × 8100 = 32400.
Problem 5
Find the square of 8101.
The square of 8101 is 65628101.
Explanation
The square of 8101 is multiplying 8101 by 8101.
So, the square = 8101 × 8101 = 65628101.
