WebCLAIM: the square root of a non prime number is rational. Take 8 for example. 8 is not prime, correct. But, √8 = √4·√2 = 2·√2. Now the 2 in √2 is prime and therefore the square root of it IS irrational, and an irrational number times a rational number is ALWAYS irrational. WebTools. In mathematics, a semiprime is a natural number that is the product of exactly two prime numbers. The two primes in the product may equal each other, so the semiprimes include the squares of prime numbers. Because there are infinitely many prime numbers, there are also infinitely many semiprimes. Semiprimes are also called biprimes.
