WebAug 8, 2024 · 4. Use the variable rules. When solving log expressions that have variables, apply the rules for combining like terms with exponents. For instance, the expression (loga_3) + (loga_3) + (loga_4) converts to a^3 + a^3 + a^4. Using the rules for like terms with exponents gives the solution 2a^3 + a^ 4.

WebThe first type of logarithmic equation has two logs, each having the same base, which have been set equal to each other. We solve this sort of equation by setting the insides (that is, setting the "arguments") of the logarithmic expressions equal to each other. For example: Solve log 2 (x) = log 2 (14). WebThe logs of negative numbers (and you really need to do these with the natural log, it is more difficult to use any other base) follows this pattern. Let k > 0 ln (−k) = ln (k) + π 𝑖 For other bases the pattern is: logₐ (−k) = logₐ (k) + logₐ (e)*π 𝑖 …
