What is the term for the product of two prime numbers?
3,033
The phrase "prime power" is usually used to refer to numbers of the form $p^n$ with $p$ prime and $n \geq 1$. I imagine "prime squared" or "prime square" is the most reasonable name for what you're describing.

Numbers that can be factored down into 2 and only 2 prime numbers, such as:
25 (5 * 5) 9 (3 * 3) 12752041 (3571 * 3571)
Is there a mathematical term for these numbers? I did a bit of Googling, but it's tough to search for what something is called.
Update: To clarify, I meant the square of a single prime number. So n * n where n is prime.

Mike Christensen almost 11 yearsWhen I looked up semiprime, it says it's a product of two prime numbers, but those prime numbers are not necessarily distinct. So 15 (3 * 5) could be semiprime, correct?

Dan Shved almost 11 yearsNot that I'm aware of. Frankly, I doubt it, cos' you can just call them squares of prime numbers.

Mike Christensen almost 11 yearsThanks! Though @cassandra0's answer was helpful too. I'm learning about cryptography, and semiprimes come up quite a bit.
