The purpose of this note is to prove the following:

THEOREM 1. If α1, α2, α3, β1, β2 are rational numbers satisfying (i) α1 > 0, α2 > 0, α3 > 0 are multiplicatively independent (ii) the size of αi, ≤ S1, i = 1, 2, 3, and that of βi, ≤ (log S1)100 = S, i = 1, 2, (100 is quite unimportant), then

| β1 log α1 + β2 log α2 - log α3 | > C(∈) exp ( - (log 1)8+∈)

where ∈ > 0 is an arbitrary fixed constant and C(∈) is an effectively computable positive constant depending only on ∈.

Abstract


The purpose of this note is to prove the following:

THEOREM 1. If α1, α2, α3, β1, β2 are rational numbers satisfying (i) α1 > 0, α2 > 0, α3 > 0 are multiplicatively independent (ii) the size of αi, ≤ S1, i = 1, 2, 3, and that of βi, ≤ (log S1)100 = S, i = 1, 2, (100 is quite unimportant), then

| β1 log α1 + β2 log α2 - log α3 | > C(∈) exp ( - (log 1)8+∈)

where ∈ > 0 is an arbitrary fixed constant and C(∈) is an effectively computable positive constant depending only on ∈.
