Question

Marek thinks of 2 prime numbers that are larger than 3. He multiplies the 2 numbers together.is his answer odd or even.

Answer 1

It must be odd. As you know, 2 is the only even prime number. Therefore, all prime numbers have the form (2x+1).
For example, two numbers are 2x+1 and 2x+5. We have:
(2x+1)(2x+5)= 4x^2 +12x+5
Since 4x^2+12x is even, 5 is odd, 4x^2+12x+5 must be odd.
Good luck!

Answer 2

Im thinking it would be odd because when you multiply 2 odd numbers youre result is usually odd
