Methods7 exponential equations

  1. 1. Maths MethodsExponential Equations K McMullen 2012
  2. 2. Exponential EquationsThe equation ax=b is an example of a generalexponential (or indicial) equationTo 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 usedlog(x)>0 if x>1Log(x)<0 if 0<x<1 K McMullen 2012
  3. 3. Exponential EquationsExponential equations (base e)Euler’s number (e) is an irrational number andhas to be approximated. e=2.718281828459…When working with Euler’s number just treat itlike you would any other number The same index laws apply The same log laws apply K McMullen 2012
