1. Chapter 8 Review

2. Rewrite into logarithm form: 1. 2.

3. Rewrite into exponential form: 3. 4. Simlify: 5. 6.

4. Use a calculator to evaluate – round to 3 decimal places 7. 8. Tell whether the function is exponential growth or decay: 9. f(x) = GROWTH.199 1.883

5. Expand: log 8 x 5 y 10. 11. log 5 5log 8 x + log 8 y log 5 5 + 2log 5 x-3log 5 y

6. Condense: 12. ln56 – ln8 ln7 13. 3log 2 x + 4log 2 y log 2 x 3 y 4

7. Use change of base formula to evaluate: log 5 11 14. 15. log 3 16 log11 log 5 1.5 log16 log 3 2.524

8. Solve: 16. 64 x-7 = 16 x+11 17. e x-2 = 8 4 3x-21 = 4 2x+22 3x-21 = 2x+22 x = 43 lne x-2 = ln8 x-2 = ln8 x = ln8+2 x=4.079

9. 2log 5 (x-1) = 4 18. 19. Log 3 (2x-3) =3 X-1 = 25 X = 26 2X-3 = 27 2x = 30 x = 15

10. 20. Continuous compounded interest uses the formula: A = Pe rt. You deposit $3000 in an account that pays 3% annual interest compounded continuously. What is the balance after 1 year? A = 3000e.03(1) $3091.36
