We establish that E (N)\ll N^ {11/32}, thus improving on an earlier result of Harman and the first author, where the exponent 7/20 appears in place of 11/32.

WebWe prove that every sufficiently large even integer can be represented as the sum of two squares of primes, four cubes of primes and 28 powers of two. This improves the result … WebApr 8, 2024 · Re: S is the sum of the reciprocals of the squares of the prime numbers be [ #permalink ] Tue Jun 02, 2024 3:41 am. The answer is A. Since if we first divide 1 by the prime numbers that appear between 19 and 41 exclusive we get 1/20+1/30+1/30+1/40= 0.13. If we square 0.13 we get 0.0169 which is approximately equal to 2*10^-4. WebJan 22, 2024 · The easiest statement is this: Proposition 1.28.1. If p is a prime and n is a nonnegative integer, then p2n = (pn)2 + 02, so any prime raised to an even power can be written as the sum of two squares. Here’s another piece of the puzzle. Lemma 1.28.2. If n ≡ 3 (mod 4), then n cannot be written as a sum of two squares. finch golf
