How to solve a log function
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 ≈ … WebIf you meant: f (x) = log₃ [ (4x-3)²] Then the domain is x≠ ¾ because that value would lead to a log of 0. The square makes sure we never get a negative value for the argument. If you mean f (x) = {log₃ [ (4x-3)}² which is usually written as log²₃ (4x-3) then: As before x≠ ¾ due to being a log of 0.

WebAug 8, 2024 · How to solve logs in expressions Use the following steps to simplify logarithmic expressions: 1. Identify the base and the power In a basic log, you can decompose the expression into its related exponential function to simplify. In the logarithm, find the base as the subscript of the log term. WebA scientific calculator generally always has an ln (natural logarithm, or log base e) key. From the change of base theorem, log base a of b = (ln b)/(ln a). For example, you can calculate log base 3 of 5 by calculating (ln 5)/(ln 3) which should give approximately 1.465.
