Name Manipulating Common Logs (Base 10) y = log, x where b = base Common logarithm b = 10. When no base is given, assume base 10. y = log, x is equivalent to 101 = x Solve without using a calculator. Example: log1 100 = y 1. log 1000 10% = 100 y = 2 2. log V10 3. log V102 4. log 0.1 5. log 0.0001 6. log V10 7. log V10 8. log 10 9. log 1 10. log 10,000
