NCERT Solutions for Class 10 Maths Chapter 1 extended by Vedantu are formulated as per the syllabus. All the questions are based on Euclid’s Division Lemma and its applications. Question number 1, 2, 3 are based on the prime factorisation method of LCM and HCF. A lemma is a proven statement used for proving another statement.. Every composite number can be expressed as a product of primes, and this factorisation is unique, apart from the order in which the prime factors occur. In each of these questions, first of all, we assume that the given number is a rational number with numerator and denominator as coprime integers. The word algorithm come from the name of the name of the 9th century Persian mathematician al-Khwarizmi. The Fundamental Theorem of Arithmetic and Euclid’s division lemma has many applications, both within mathematics and in other fields. At last in Question 7, we have to find out a number which is divisible by both 12 and 18 that is LCM of the two numbers. In order to solve problem in a better way, first you need to understand the concepts. Isn’t it what you wanted?. 3. In Exercise 1.2 of Class 10 Maths, the Fundamental Theorem of Arithmetic is main to solve the questions. 3825 को अभाज्य गुणनखंडो के गुणनफल के रूप में व्यक्त कीजिए।, 510 और 92 के HCF और LCM ज्ञात कीजिए तथा इसकी जाँच कीजिए कि दो संख्याओं का गुणनफल = HCF×LCM है।. So, students can download UP Board Solutions for Class 10 Maths Chapter 1 from this page. Improve Your Career with Online Certification Programs. 6 is divisible by 2 so it is a even number, 6 is divisible by 2 but 1 is not divisible by 2 so it is a odd number, 6 is divisible by 2 and 2 is also divisible by 2 so it is a even number, 6 is divisible by 2 but 3 is not divisible by 2 so it is a odd number, 6 is divisible by 2 and 4 is also divisible by 2 it is a even number, 6 is divisible by 2 but 5 is not divisible by 2 so it is a odd number, Therefore, the cube of any positive integer is of the form 9. NCERT Solutions Class 10 Maths Chapter 1 Real Numbers is a result of untiring efforts of our expert faculties to aid you with ample of thoroughly revised solutions and key facts related to the chapter. Step 1: Apply Euclid’s division lemma, to c and d. So, we find whole numbers, q and r such that c = dq + r, 0 £ r < d. Step 2: If r = 0, d is the HCF of c and d. If r ≠ 0, apply the division lemma to d and r. Step 3: Continue the process till the remainder is zero. If they are rational, and of the form.
