Updated for **NCERT 2023-2024 Book.**

Answers to all exercise questions and examples are solved for** Chapter 1 Class 10 Real numbers.** Solutions of all these NCERT Questions are explained in a step-by-step easy to understand manner

In this chapter, we will study

- What is a
**Real Number** - What is
**Euclid's Division Lemma**, and - How to find
**HCF**(Highest Common Factor) using Euclid's Division Algorithm - Then, we study Fundamental Theorem of Arithmetic, which is basically
**Prime Factorisation** - And find
**HCF and LCM**using Prime Factorisation - We also use the formula of HCF and LCM of two numbers a and b
**HCF × LCM = a × b** - Then, we see what is an
**Irrational Number** - and
**Prove numbers irrational**(Like Prove**√**2,**√**3 irrational) - We revise our concepts about
**Decimal Expansion**(Terminating, Non-Terminating Repeating, Non Terminating Non Repeating) - And find out Decimal Expansion of numbers
**without performing long division**
