LOGARITHM











                                   • Logarithm functions are the inverse of exponential

                                        functions.





                                                                  x
                                   • Example   3 = 9                                        x = ?

                                                                the answer is 2



                                                                          2
                                                                i.e 3 = 9                      Exponential form



                                        In terms of logarithmic form, we can say that



                                                                x = log 9
                                                                              3
                                                                                               Logarithmic form

                                                                x = log 9

                                                       i.e      x = log 3          2            x = 2(1) = 2
