Find all numbers p such that p and p^2 are both prime. prove that you found them all

0 and 1 are neither prime nor composite. A prime is any number greater than 1 that has just 1 and itself as factors. Primes can only start at x > 1

When that happens (when you start with numbers greater than one) p^2 is a composite consisting of 2 primes, so any composite will obey the law that he number will have at least 3 factors making it up -- in this case p p^2 and 1.

So the answer to the question by definition is that 0 numbers can have the property of both p and p^2 to be prime.

There are no such numbers. No prime number is a square of any integer.

If is a prime number, then it's divisible only by 1 and (itself).

If

then

As we can see is divisible not only by 1 and (itself), but also by , which means it can't be a prime number.

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.
