Solving Exponential Equations With A Common Base

                     Lesson 1

 

                                                 Problem:    Solve the exponential equation: 50x + 5 = 2500                                                                                                 

                                                            Solution       50x+5    = (50)2     

                                                            Step 1:                         

                           

                                                            Step 2:       x+5  = (50)2 

                      

                                                            Solution       x+5  = 2                      

                                                            Step 3:   

 

                                                            Solution       Answer: -3                           

                                                       

 

 

                                                            Try two practice problems:  

 

A.

11-3 = 11x-4

B.
