Step 2: Multiply the number by itself using the multiplication button (×). That is 769 × 769.
Step 3: Press the equal to button to find the answer. Here, the square of 769 is 591361.
Tips and Tricks for the Square of 769
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 769
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 769² with (7 + 6 + 9)² or (700 + 60 + 9)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 769
Problem 1
Find the length of the square, where the area of the square is 591361 cm².
The area of a square = a²
So, the area of a square = 591361 cm²
So, the length = √591361 = 769.
The length of each side = 769 cm
Explanation
The length of a square is 769 cm.
Because the area is 591361 cm², the length is √591361 = 769.
Problem 2
Alice is planning to carpet her square room of length 769 feet. The cost to carpet a foot is 5 dollars. Then how much will it cost to carpet the full room?
The length of the room = 769 feet
The cost to carpet 1 square foot of room = 5 dollars.
To find the total cost to carpet, we find the area of the room.
Area of the room = area of the square = a²
Here a = 769 Therefore, the area of the room = 769² = 769 × 769 = 591361.
The cost to carpet the room = 591361 × 5 = 2956805.
The total cost = 2956805 dollars
Explanation
To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per foot.
So, the total cost is 2956805 dollars.
Problem 3
Find the area of a circle whose radius is 769 meters.
The area of the circle = 1,857,258.14 m²
Explanation
The area of a circle = πr²
Here, r = 769
Therefore, the area of the circle = π × 769² = 3.14 × 769 × 769 = 1,857,258.14 m².
Problem 4
The area of the square is 591361 cm². Find the perimeter of the square.
The perimeter of the square is 3076 cm
Explanation
The area of the square = a²
Here, the area is 591361 cm²
The length of the side is √591361 = 769
Perimeter of the square = 4a
Here, a = 769
Therefore, the perimeter = 4 × 769 = 3076 cm.
Problem 5
Find the square of 770.
The square of 770 is 592900
Explanation
The square of 770 is multiplying 770 by 770.
So, the square = 770 × 770 = 592900
