Name___________________________________________ Honors Algebra I Exponential and Logarithmic Functions Review Write each equation in its equivalent exponential form 1. 1 log 343 7 3 2. log 1 64 x 2 Write each equation in its equivalent logarithmic form. 3. 6 x 216 4. 13y 874 Evaluate each expression WITHOUT a calculator. If evaluation is not possible, state the reason. 5. log 6 1 36 9. log 6 3 6 2 log 4 410 11. log 3 log 3 1 log 4 (16) 10. log 3 (log 5 5) 13. 10 log4 x 12. 7. 8. 6. log 4 256 5log5 5 2 Use the properties of logarithms to expand each logarithmic expression as much possible, Where possible, evaluate the logs. 14. 36x 3 log 2 y 15. xy 2 log 64 16. (3xy) 3 log 2 (9xz) Use the properties of logarithms to condense each logarithmic expression into a single logarithm. 17. 7log x 3log y 4log z 18. 1 log 4 x log 4 y log 4 z 3 Solve each exponential equation. If necessary, round t0 the nearest hundredths place. 19. 2 4 x 2 64 9 x 2 27 x 20. 21. 3x 4 7 2x 1 Solve each logarithmic equation. Round all answers to the nearest hundredths place. 22. log 4 (2x 5) 3 24. log 3 (x 1) log 3 (x 2) 2 25. log( 2x 1) log( x 3) log( x 5) 23. 3 4log( 2x) 15 26. How long, the nearest tenth of a year, will it take $30,000 to triple in value at 7.5% annual interest compounded monthly? Compounded continuously?
