NCERT Solutions for Class 8 Maths Chapter 5 Squares and Square Roots

The NCERT Solutions for Class 8 Maths Chapter 5 Squares and Square Roots help you learn about numbers multiplied by themselves. This guide provides clear answers to all textbook exercises. You will learn to find square roots using simple methods like prime factorisation and long division. It's a great way for students to improve their math skills easily.

Understanding squares is like learning a fun secret code in math. When you multiply a number by itself, you get its square. For example, 2 times 2 is 4, so 4 is the square of 2. These square and square roots class 8 questions and answers explain every step clearly. We use simple words so you can follow along without any trouble.

• Perfect Squares: These are numbers like 1, 4, 9, and 16.

• Square Roots: This is the opposite of squaring a number.

• Ending Digits: You can tell a lot about a square by its last digit.

• Calculation Tips: We show you how to solve problems quickly.

You don't need to worry about hard sums anymore. Our square and square roots class 8 ncert solutions make learning very fast. We focus on making the logic easy to see. If you follow these steps, you will find math very interesting.

Properties of Square Numbers

Square numbers have special rules that make them easy to spot. For instance, a square number never ends in 2, 3, 7, or 8. If you see a number ending in these, it is not a perfect square. This is a vital part of solving square and square roots class 8 questions and answers.

We can also find squares by looking at patterns. Adding odd numbers is a great trick. For example, 1 + 3 = 4, which is the square of 2. Then, 1 + 3 + 5 = 9, which is the square of 3. These patterns are part of the square and square roots class 8 important questions with answers you will see in exams.

Finding Square Roots Methods

A square root is a value that gives the original number when multiplied by itself. To find it, we often use the prime factorisation method. You just break the number into its smallest parts. Then, you make pairs of the same numbers. This is a simple way to handle square and square roots class 8 questions and answers problems.

1. Prime Factorisation: Break the number into prime factors.

2. Make Pairs: Group the same factors in twos.

3. Multiply: Take one from each pair and multiply them.

4. Repeat Subtraction: Keep taking away odd numbers until you reach zero.

The long division method is also very useful for large numbers. It looks like normal division but has a few different steps. We explain this in our NCERT Solutions for Class 8 Maths Chapter 5 – Squares and Square Roots section. It helps you find roots of numbers that aren't easy to factor.

Pythagorean Triplets Explained Simply

A Pythagorean triplet is a set of three numbers where the sum of squares of two numbers equals the square of the third. A common example is 3, 4, and 5 because 9 + 16 = 25. We use the formula 2m, (m² - 1), and (m² + 1) to find these sets. This is a common topic in square and square roots class 8 ncert solutions.

• Formula: For any number m > 1, the triplet is (2m, m²-1, m²+1).

• Example: If 2m = 6, then m = 3.

• Result: The triplet becomes 6, 8, and 10.

When you practice these, you will see how they fit together. It is like a puzzle that always works. These triplets are used in building things and in geometry. Understanding them is a vital part of your square and square roots class 8 important questions with answers study plan.

Finding Roots of Decimals

Working with decimals might seem scary, but it is just like whole numbers. You just need to place the decimal point in the right spot. In NCERT Solutions for Class 8 Maths Chapter 5 Squares and Square Roots, we show you how to pair digits from the decimal point. You pair them to the left and to the right.

• Step 1: Put bars over pairs of digits.

• Step 2: Start dividing from the left-most bar.

• Step 3: Place the decimal in the answer when you cross the decimal in the sum.

By following this, you can solve any decimal problem. Many students find this tricky, but our square and square roots class 8 questions and answers make it plain. Practice makes you better at this every day. You will soon find that decimals are quite easy to manage.

Solving Word Problems Easily

Word problems tell a story about math. Sometimes they ask about the number of rows in a garden. If the number of rows and plants are the same, you just find the square root. These are the most fun square and square roots class 8 important questions with answers. You apply what you learned to real-life situations.

1. Read: Understand what the question is asking for.

2. Identify: See if you need to find a square or a root.

3. Solve: Use the method you like best, like division or factors.

4. Check: Multiply your answer by itself to see if it matches.

At the end of the day, these solutions are here to help you grow. We don't want you to just memorize; we want you to understand. Using square and square roots class 8 questions and answers can help you revise. Keep practicing and you will do great in your school tests.
