Name:____________________________ Ch 3 Test 2 Review Solve the equation. Circle your final answer.
1. log! 𝑥 + 6 = log! 3𝑥 − 6
2. ln 765 = ln 𝑥
3. −6− 7 log! −4𝑏 − 9 = −6
4. log 𝑥! − log −5𝑥 = 2
5. 3!!!! = 81
6. 𝑒! = 256
7. 4 5!! = 48
8. 𝑒!! − 2𝑒! − 15 = 0
9. 3!!! = 2!!!
10. 4!!! = !!
!
11. log! 𝑥 − 2 + log! 𝑥 + 3 = log! 14
12. 5!!!! = 5!!!
13. ln 5𝑥 = −2
14. log 𝑥 + log 3 = log 18
15. log(7𝑥 + 3)− log 𝑥 + 1 = log 2𝑥
16. 12! = 12!"#
