Let k be an integer with k >= 3. Let lambda(1), lambda(2), lambda(3) be non-zero real numbers, not all negative. Assume that lambda(1)/lambda(2) is irrational and algebraic. Let nu be a well-spaced sequence, and delta > 0. In this paper, we prove that, for any epsilon > 0, the number of v is an element of nu with v <= X such that the inequality.vertical bar lambda(1)p(1)(2) + lambda(2)p(2)(2) + lambda(3)p(3)(k) - v vertical bar < v(-delta).has no solution in primes p(1), p(2), p(3) does not exceed O(X1-2/(7m2(k))+2 delta+epsilon) where m(2)(k) relies on k. This refines a recent result. Furthermore, we briefly describe how a similar method can refine a previous result on a Diophantine problem with two squares of primes, one cube of primes and one k-th power of primes.
