CLASS 10 MATHS | Chapter - 1 Real Numbers | NCERT Full Explanation with Questions

Описание: This chapter builds upon your earlier understanding of number systems and explores the properties of real numbers in greater depth. It begins with the basis for finding the HCF (Highest Common Factor) and LCM ( Least Common Factor) of two numbers. The chapter then covers the Fundamental Theorem of Arithmetic, which states that every composite number can be expressed uniquely as a product of prime numbers (apart from the order of the factors).

Further, the chapter discusses:

The relationship between HCF and LCM using prime factorization.

The concept of irrational numbers, especially proving numbers like /2, √3, and others as irrational.

This chapter is important for understanding the structure of the number system and lays a strong foundation for higher ma' tics.
