Prime numbers are only divisible by 1 and themselves. So, a Prime number cannot be divisible by 10. The only prime number that is divisible by 2 is 2 itself; all other numbers divisible by 2 are not prime numbers.

What is 80 as a product of prime numbers?

80 is an even number, thus it is divisible by 2; 80/2 = 40. 40 is also even, so it too is divisible by 2; 40/2 = 20. The same applies to 20; 20/2 = 10, and to 10; 10/2 = 5. Since both 2 and 5 are prime numbers, the prime factorization of 80 is 24 X 5.

Is the only even prime number is 2 t or f?

Yes, it is true that 2 is the only even prime number. All even numbers are evenly divisible by 2 (that is the definition of an even number). The number 2 is also divisible by 2, however, prime numbers, like all numbers, are evenly divisible by themselves, so that does not disqualify 2 from being a prime number.
