Solving equations involving logarithms and exponentialsSolve, ExampleWriting, Solution
Exponential equations can be solved by taking the log of both sides.Steps:1) As much as possible, get the log by itself.2) Take the log (or natural log) of both sides.3) Simplify as needed using the log rules.4) Solve the equation for the variable.Examples...
Using logarithms to solve equations with exponentials See the lessons on logarithms elsewhere in this collection for information regarding the properties of logarithms. An equation which can be recast into the formax=bcan be solved forxin terms of logarithms:x=logab. Example:Findxsuch...
Solving Logarithmic Equations Lesson Summary Frequently Asked Questions How do you solve logarithms step by step? 1. If the unknown is outside the log, then evaluate the log. Most logs need a calculator to evaluate. 2. If the unknown is inside the log, convert to exponential form. 3....
Solving Logarithmic Equations Basic Technique for Solving Logarithms If an equation with logarithms can be solved using algebraic techniques, then those techniques will generally involve the product, quotient, and power rules of logarithms—applied in either direction—as well as examining the problem for...
Solving Exponential Equations Solving Exponential Equations The solution to the exponential equation can be represented using logarithms: Use the sliders below to modify and in the equation . Click Solve to show the steps of the solution and display...
Logarithms cannot have non-positive arguments (that is, arguments which are negative or zero), but quadratics and other equations can have negative solutions. When we convert a log equation to a different type of equation by equating the insides of the logs, we may be "creating" solutions th...
