                                        Problem:



                                                                    n
                                                      50 = 2 ,    n = ?






                                        Solution:


                                                      Write an equivalent logarithmic form


                                                                                       y
                                                      (Remember: x = a ---> log x = y)
                                                                                                         a
                                                                                  log 50 = n
                                                                                         2

                                                                                    log 50/ log 2 = n
                                                                                                           10
                                                                                          10
                                                                                    n= 5.645
