WebFeb 2, 2024 · Because for t → 0 we have log ( 1 + t) ≈ t, we can conclude that x ≈ 3, but x < 3. The numerical value is about 2.8135880922155955. If you want, you can use the infinite series for log ( 1 + t), however, you need to remember that in your case the change of base is necessary: log 3 ( 1 − 5 27) = 1 log 3 log ( 1 − 5 27) = − 1 log ... WebTo solve for y, first take the log of both sides: log 5 = log 3 y. By the identity log x y = y · log x we get: log 5 = y ⋅ log 3. Dividing both sides by log 3: y = log 5 log 3. Using a calculator we can find that log 5 ≈ 0.69897 and log 3 ≈ …
