Tips and Tricks for the Square of 839
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 839
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 839² with (8 + 39)² or (800 + 39)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 errors.
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 839
Problem 1
A large painting is square-shaped and its area is 703,921 square inches. What is the length of one side of the painting?
The area of a square = a² So, the area of a square = 703,921 square inches So, the length = √703,921 = 839. The length of each side = 839 inches
Explanation
The length of a square is 839 inches.
Because the area is 703,921 square inches, the length is √703,921 = 839.
Problem 2
Alice wants to install a square-shaped tile on her patio. Each tile has a side length of 839 cm. If the cost to install per square cm is $0.50, what is the cost to install one tile?
The length of the tile = 839 cm The cost to install 1 square cm of tile = $0.50 To find the total cost to install, we find the area of the tile, Area of the tile = area of the square = a² Here a = 839 Therefore, the area of the tile = 839² = 839 × 839 = 703,921. The cost to install the tile = 703,921 × 0.50 = $351,960.50. The total cost = $351,960.50
Explanation
To find the cost to install the tile, we multiply the area of the tile by the cost to install per square cm.
So, the total cost is $351,960.50.
Problem 3
Find the area of a circle whose radius is 839 meters.
The area of the circle = 2,212,402.64 m²
Explanation
The area of a circle = πr²
Here, r = 839
Therefore, the area of the circle = π × 839² = 3.14 × 839 × 839 = 2,212,402.64 m².
Problem 4
A square plot has an area of 703,921 m². What is the perimeter of the plot?
The perimeter of the plot is 3,356 m.
Explanation
The area of the square = a²
Here, the area is 703,921 m²
The length of the side is √703,921 = 839
Perimeter of the square = 4a
Here, a = 839
Therefore, the perimeter = 4 × 839 = 3,356.
Problem 5
Find the square of 840.
The square of 840 is 705,600.
Explanation
The square of 840 is multiplying 840 by 840.
So, the square = 840 × 840 = 705,600.
