To solve a logarithmic equations use the esxponents rules to isolate logarithmic expressions with the same base. Set the arguments equal to each other, solve the equation and check your answer. A logarithmic equation is an equation that involves the logarithm of an expression containing a varaible. The three types of logarithms are common ...
- Exponential
Then, take the logarithm of both sides of the equation to...
- Exponential
The change of base formula helps us manipulate logarithmic expressions by rewriting them in bases of 10 or e. This formula involves finding the ratios between the logarithms between the original argument and base.
How to solve logarithm expessions by re-writing the logarithm as an exponential equation
25 Μαΐ 2021 · When given an equation of the form \({\log}_b(S)=c\), where \(S\) is an algebraic expression, we can use the definition of a logarithm to rewrite the equation as the equivalent exponential equation \(b^c=S\), and solve for the unknown.
