Methods7 exponential equations
Download as PPTX, PDF0 likes599 views
This document discusses how to solve exponential equations. It explains that to solve ax=b, you make the bases or indexes the same. It also notes that logs can be used if the base cannot be written the same. It then discusses exponential equations with base e, noting that e is an irrational number that is approximated as 2.718281828459. It states the same index and log laws apply when working with e as with any other number.

- 2. Exponential Equations The equation ax=b is an example of a general exponential (or indicial) equation To solve these equations: If the unknown is an index make the bases the same If the unknown is a base then make the index the same If the base is not the same and the numbers can not be written with the same base, then logs can be used log(x)>0 if x>1 Log(x)<0 if 0<x<1 K McMullen 2012
- 3. Exponential Equations Exponential equations (base e) Euler’s number (e) is an irrational number and has to be approximated. e=2.718281828459… When working with Euler’s number just treat it like you would any other number The same index laws apply The same log laws apply K McMullen 2012
