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 159.
Step 1: Identify the number. Here, the number is 159.
Step 2: Multiplying the number by itself, we get, 159 × 159 = 25,281. The square of 159 is 25,281.
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 159. So: 159² = 159 × 159 = 25,281
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 159.
Step 1: Enter the number in the calculator Enter 159 in the calculator.
Step 2: Multiply the number by itself using the multiplication button (×). That is 159 × 159
Step 3: Press the equal to button to find the answer Here, the square of 159 is 25,281.
Tips and Tricks for the Square of 159 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 159
Mistakes are common 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.
Mistake 1
Calculation errors:
Calculation errors mostly happen when students skip the steps or swap 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 while using the formula.
The formula to find the square of the number is a². Instead, students may use 159² with (1+5+9)² or (150+9)². So students should check and use the correct formula and double-check the answers to avoid all the confusion.
Mistake 3
Confusing square and square root.
Not understanding the concept of square and square root can lead to confusion. 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 159
Problem 1
Find the length of the square, where the area of the square is 25,281 cm².
The area of a square = a² So, the area of a square = 25,281 cm² So, the length = √25,281 = 159. The length of each side = 159 cm
Explanation
The length of a square is 159 cm.
Because the area is 25,281 cm², the length is √25,281 = 159.
Problem 2
Tom is planning to paint his square wall of length 159 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 159 feet The cost to paint 1 square foot of wall = 3 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 = 159 Therefore, the area of the wall = 159² = 159 × 159 = 25,281. The cost to paint the wall = 25,281 × 3 = 75,843. The total cost = 75,843 dollars
Explanation
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 75,843 dollars.
Problem 3
Find the area of a circle whose radius is 159 meters.
The area of the circle = 79,390.26 m²
Explanation
The area of a circle = πr²
Here, r = 159
Therefore, the area of the circle = π × 159²
= 3.14 × 159 × 159
= 79,390.26 m².
Problem 4
The area of the square is 25,281 cm². Find the perimeter of the square.
The perimeter of the square is 636 cm.
Explanation
The area of the square = a²
Here, the area is 25,281 cm²
The length of the side is √25,281 = 159
Perimeter of the square = 4a
Here, a = 159
Therefore, the perimeter = 4 × 159 = 636 cm.
Problem 5
Find the square of 160.
The square of 160 is 25,600.
Explanation
The square of 160 is multiplying 160 by 160.
So, the square = 160 × 160 = 25,600
