Logarithmic Equations

Logarithmic Equations

1. Properties

   • log b raised to y base b is
   • Base should be greater than 1
   • We can't take the log of a negative number
   • Euler’s number which is approximately 2.718

2. Exponential Functions

   • Logarithm is used if exponential equations don’t have any common bases
     • Logarithms are inverses of Exponentials
     • We are able to use its properties

3. Change of Base Formula

   • It’s not necessarily base 10. It depends on whoever is answering

4. Common Logarithms

   • A common logarithm is any logarithm with base 10

5. Natural Logarithms

   • the base of a natural logarithm is the special number e
