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.

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
