Question

Every composite number can be expressed (factorised) as a product of primes, and this factorisation is unique apart from the order in which the prime factors occur.

• A. True
• B. False
• C. Neither
• D. Either

Answer 1

Answer: (A)

This is true as any composite number can be expressed in terms of its prime factors. The prime factors for 2 numbers can be same but their combination is unique.
Example,
$12=2^2\ast 3$ and $18=2\ast 3^2$
Both have prime factors as 2 and 3 but the combination that 12 has is different from that of 18.
