Proving the Division Property of Prime Numbers in Positive Integers

Click For Summary
SUMMARY

The discussion centers on proving the division property of prime numbers, specifically that if a prime number P divides a^6 and a^3 + b^7, then P must also divide b. The key equations referenced include the properties of divisibility, particularly that if P divides a^6, it follows that P divides a. This leads to the conclusion that since P is prime, it must also divide any linear combination involving a and b, thus establishing the required proof.

Homework Statement



(2) P is a prime number and a and b are positive integers .
We Know...
p | a^6 \
and
p | a^3 + b^7.
how do i find out how to prove that p | b?



Homework Equations


if a | b, then a | bx for every x in Z
if a | b, and a | c, then a | bx + cy for any x,y in Z.



The Attempt at a Solution


p | (a^3)(a^3)


p | a^6(n) + (a^3 + b^7)m for any m,n in Z.

I can't figure anything out about b :(

Do you know about prime factorization? If p|a^6 then p|a, doesn't it?
 
we don't know enough about a to be able to say that?
 
If p is prime, then yes you do.
