Comparing large prime powers.

Comparing large prime powers.
I have two very large primes (a, b) , each raised to a large (non-prime) integer powers (p,q) .
I want to evaluate the comparison:
a^p >= b^q
However, I don't want to attempt to calculate a^p, b^q since the results w... | {"url":"http://mathhelpforum.com/number-theory/162536-comparing-large-prime-powers-print.html","timestamp":"2014-04-18T14:33:05Z","content_type":null,"content_length":"8347","record_id":"<urn:uuid:9c12efc9-ba3a-412d-afe9-c182d3866b5e>","cc-path":"CC-MAIN-2014-15/segments/1397609533689.29/warc/CC-MAIN-20140416005213-004... |

Letting R be a commutative ring, and letting I = {a in R | a^n =0 for some n in S} where S is the set of positive integers.
Prove I is an ideal of R.
This is just saying that the nilradical is an ideal.
