SUMMARY
This discussion focuses on estimating logarithmic values using basic logarithmic properties. Participants utilized known values such as log(2) ≈ 0.30 and log(∏) ≈ 0.5 to derive log(4), log(5), log(6), and log(8). The method of linear interpolation was suggested for estimating log(5), calculated as log(5) ≈ (1/2)(log(4) + log(6)). Additionally, the relationship log(5) = log(10) - log(2) was confirmed, yielding log(5) ≈ 0.7.
