Topics Covered in Exercise 1.1 Class 10 Mathematics Questions
NCERT solutions for class 10 maths chapter 1 Real Number ex 1.1 is concerned with some of the important topics, their properties and theorem mentioned below.
1. | Fundamental Theorem of Arithmetic |
2. | Euclid’s Division Lemma |
1. Fundamental Theorem of Arithmetic - students will find that each prime number has its own way of being expressed as a prime number. This property of prime numbers is known as the fundamental theorem of arithmetic.
Basically, if an integer is greater than 1, it's either a prime number or it can be represented as a prime. All numbers can be represented as the product of their prime factors.
2. Euclid’s Division Lemma - Euclid's Division Lemma states that if we have two positive integers a and b, there exists a unique integer q and r that satisfies the condition that a = bq+r where (0 ≤ r < b).
Euclid's division algorithm is based on the Euclid's division lemma. We can use Euclid's division algorithm to figure out the HCF of 2 positive integers, a and b.
Theorem 1.1 Fundamental Theorem of Arithmetic - Every composite number can be expressed (factorized) as a product of primes, and this factorisation is unique, apart from the order in which the prime factors occur.
