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

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
