Lesson 3

derive the logarithmic laws from the index laws and use the algebraic properties of logarithms to simplify and evaluate logarithmic expressions. log a m + log a n = log a ( mn ) , log a m - log a n = log a m n , log a m n = n log a m , log a a =1, log a 1=0, log a 1 x =- log a x. ................
