Yeah, that does help. I fell better about the 2nd part of the proof.Petek said:@kathrynag,
When you have an "iff" problem, you really have to solve two problems. Here's a restatement of the problem to make this more clear:
Let a > 1 be an integer.
1. Assume that a is a square. Prove that every exponent in its prime factorization is even.
2. Assume that every exponent in a's prime factorization is even. Prove that a is a square.
Does this help?
hgfalling said:It's not an even number; the exponents are even.
So in the prime factorization of a, [itex]{a_1,a_2,...,a_n}[/itex] are even. Now what does that mean about the square root of a?

The first part still worries me.
Assume n is a square. Then we have a=n^2
That's about as far as I get with that one.
I know what I need to prove, but it's getting there.
n^2=p1^a1p2^a2...pn^an
Abstract prime factorization proof is a mathematical method used to prove that a given number is prime. It involves breaking down the number into its prime factors and showing that there are no other factors besides the number itself and 1.
Regular prime factorization involves finding the prime factors of a number using a specific algorithm, whereas abstract prime factorization proof is a more general method that can be applied to any number without the use of a specific algorithm.
Abstract prime factorization proof is important because it allows us to prove the primality of any number, regardless of its size. This is useful in many fields of mathematics and has practical applications in cryptography and computer science.
The steps involved in abstract prime factorization proof are: 1) Write the number as a product of its prime factors; 2) Show that there are no other factors besides the number itself and 1; 3) Use the Fundamental Theorem of Arithmetic to prove that the number is prime.
One common misconception is that abstract prime factorization proof only works for small numbers, when in fact it can be applied to any number. Another misconception is that it is a complicated and time-consuming process, when in reality it can be done efficiently with the right techniques.
