All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.
Example: 210
210 Divide by two.
105,2 Divide by three.
35,3,2 Divide by five.
7,5,3,2 Stop. All the factors are prime.
2 x 3 x 5 x 7 = 210
That's the unique prime factorization of 210.

Every positive composite number only has one unique prime factorization.
No. Every composite number has one unique prime factorization. You can write it with or without exponents, but it's still the same prime factorization.
Every composite number has its own unique prime factorization.
Only if they're the same number. Every composite number has a unique prime factorization.
A prime factorization is the unique way to list any integer greater than 1 as a product of prime numbers. An example of the prime factorization of a composite number is 20=2*2*5 or 20=2^2*5. The prime factorization of a prime number is itself. e.g. 11=11.
