Does there exist 2 distinct prime numbers such that their product is a square number?

Give your answer as Yes or No and explain.

NO.

Step-by-step explanation:

If the 2 prime numbers are odd then the product cannot be a square number because the only factors are the original prime numbers. If one of the prime numbers is 2 then the product will be an even number, but again the only factors will be 2 and the other prime number.

So the answer is No.
