Logarithms Exercise

1. Find values of the following:
    (log25-log22) / log 2 1/2

2. Given that log 2 = 0.301, log 3 = 0.477 and log 7 = 0.845
  Evaluate:
  a. log 5                b. log 6                   c. log 3.5

3. If log 2 = a and log 3 =b then express in terms of a and b the values of:
  a. log 12              b. log 54                c. log 1/18

Important Logarithmic Formulae:
1. alog bc = alog b + alog b
2. alog b/c = alog b – alog b
3. alog bq = q alog b
