Key Topics to Revise
The Fundamental Theorem of Arithmetic
- Every composite number can be expressed as a product of primes in a unique way (except for order)
- Prime factorization is the process of writing a number as a product of its prime factors
- This theorem forms the foundation for finding HCF and LCM using prime factorization method
Applications of Fundamental Theorem of Arithmetic
- Determining if numbers ending in zero exist for certain forms like 4ⁿ
- Solving real-world problems involving LCM (meeting times, events, cycles)
- Finding HCF for practical applications (arranging objects, dividing quantities)
Revisiting Irrational Numbers
- Irrational numbers cannot be expressed as p/q where p, q are integers and q ≠ 0
- √2, √3, √5, and √p (where p is prime) are all irrational
- Proof by contradiction is used to prove irrationality
