Maths chapter 1 real number formulas
Here are some key formulas related to real numbers in Class 10 Maths Chapter 1:
1. Euclid's Division Lemma: a = bq + r, where 0 ≤ r < b
2. HCF (Highest Common Factor): The largest number that divides two or more numbers without leaving a remainder.
3. LCM (Least Common Multiple): The smallest number that is a multiple of two or more numbers.
4. Product of two numbers = HCF × LCM
5. √2, √3, √5, etc. are irrational numbers, meaning they cannot be expressed as a finite decimal or fraction.
Some important properties of real numbers include:
- Commutative property: a + b = b + a and ab = ba
- Associative property: (a + b) + c = a + (b + c) and (ab)c = a(bc)
- Distributive property: a(b + c) = ab + ac
These formulas and properties form the foundation of real numbers in Class 10 Maths. Do you need help with any specific problems or concepts?
