Unformatted text preview: of 5000 is only 0.69897 bigger than the log base 10 of 1000. This is because 5000 is not an order of magnitude, or power of 10, larger than 1000. The log 10 of 5000 has to be between 3 and 4 (because the number 5000 is between 103 and 104) Logarithms The Log Scale 1 10 6 10 5 10 3 10 4 10 1 10 2 20 30 40 10 2 3 4 200 300 400 2000 3000 4000 0 1 2 3 4 5 6 7 8 9 10 Graph these points: (7, 10) (3, 6) (6, 20000) (5, 300000) Logarithms The Log Scale 1 10 6 10 5 10 3 10 4 10 1 10 2 20 30 40 10 2 3 4 200 300 400 2000 3000 4000 0 1 2 3 4 5 6 7 8 9 10 Graph these points: (7, 10) (3, 6) (6, 20000) (5, 300000) Logarithms Logs in bases other than 10 work the same way as logs of base 10: Log 2 (4) = ? 2?=4 ?=2 Log 2 (16) = ? 2?=16 ?=4 Log 2 (25) = ? 2?=25 ?=4.64...
