  4-7  Exponential Functions 
     Definition: 
      
     Exponential equations are equations in 
     which variables occur as exponents.

   When the bases are the same, we can 
   just set the exponents equal and solve.

   When the bases are NOT the same, we 
   must make them equal before we solve.
