Who is asking: Student Question: " Use pairs of prime numbers to find all the numbers less than 50 that have only two prime factors. Make an organized list." I understand prime and composites but just don't understand this question. Please help. Thank you. Nikolas 

Hi Nikolas, I started a list of primes to see what they can be. I got
The next smallest prime is 29 and the smallest product of 29 with another prime is 229 which is larger than 50. Start with 2. What products of 2 with one other prime give a number less than 50?
What product of two 2's with one other prime give a number less than 50?
What product of three 2's with one other prime give a number less than 50?
What product of four 2's with one other prime give a number less than 50?
This is the entire list of numbers less than 50 that have two prime factors, one of which is 2. Next try 3. What products of 3 with one other prime larger than 3 give a number less than 50?
Can you complete the list? Penny
