log 343 = 3 7 Evaluate: lg 100 lg 100 = log10100 Let x = log10100 then 2 10 100 10 x = = from which, x = 2 Hence, lg 100 = log10100 = 2 8 Evaluate: lg 0 01

argument For example: Log10100 asks the question 10 to what power equals 100? Log10100 = 2 because 102 = 100 For example: log28 asks the question 2
