What are the twin primes that are greater than 20 but less than 20?
The twin primes that are greater than 20 but less than 30 are (23, 25) and (29, 31). However, since 25 is not prime, the only valid twin primes in that range are (29, 31). Twin primes are pairs of prime numbers that have a difference of two.
What is the product of primes for 20?
2 x 2 x 5 = 20
What number has the product of exactly three different prime numbers?
Since there are infinitely many primes, there are infinitely many numbers that are products of 3 primes.
Can a product of primes be split into sum of three products of primes?
Sure. All composite numbers can be written as a product of primes. It shouldn't be tough to find a composite number that's the sum of three other composite numbers. Let's try 30. 2 x 3 x 5 = 30 Product of primes, check. 6 (2 x 3) + 10 (2 x 5) + 14 (2 x 7) = 30 Sum of three products of primes, check.
How many primes are there in between 0 and 20?
There are 9 prime numbers between 0 and 20: 1,2,3,5,7,11,13,17,19.
What is the product of the primes?
The products of the primes are the composites.
Write 20 as a product of primes?

What is the product of primes for 20?
2 x 2 x 5 = 20
What is 24 as products of primes using exponents?
