- 1. Multiple Choice
Rewrite log28 = 3 in exponential form
28 = 3
23 = 8
32 = 8
83 = 2
- 2. Multiple ChoiceRewrite the equation into logarithmic form:
62 = 36log6 2 = 36log6 36 = 2ln 36 = 2636 = 2 - 3. Multiple ChoiceWrite in exponential form.
log2(1/8) = -32-3 = 1/821/8 = -3-32 = 1/8-31/8 = 2 - 4. Multiple Choice
Write in logarithmic form
2-4 = 1/16
log2(1/16) = -4
log-4(1/16) = 2
log -4 2 = 1/16
log2(-4) = 1/16
- 5. Multiple Choice
To evaluate a logarithm statement log981, you think "9 to what power is 81".
True, and it's 2
False
- 6. Multiple Choice
Evaluate the log by thinking " 3 to what power is 1/9" so
log3(1/9) =
1/2

- 13. Multiple ChoiceRe-write in log form 26=64log26=64log264=6log642=6log646=2
- 14. Multiple ChoiceRe-write in exponential form log5625=45625=454=62545=62542=16
- 15. Multiple ChoiceChange to Exponential Form:
log636 = 226=3662=36362=6366=2 - 16. Multiple ChoiceRewrite logpt = m in exponential form.pt = mtm = pmt = ppm = t
- 17. Multiple ChoiceRewrite in logarithmic form. 70=1log07=1log70=1log71=0log17=0
