11th Grade Logarithms and Exponential Equations Worksheet — Level 1 — Practice Set 4 — Answers
logₐ y = x means ax = y. Log laws: log a + log b = log ab; log a − log b = log (a ÷ b); log aⁿ = n log a.
1.Write 103 = 1000 in logarithm form.
Answer: log₁₀ 1000 = 3
ax = y means logₐ y = x.
2.Evaluate log₁₀ 100.
Answer: 2
102 = 100
3.Write 101 = 10 in logarithm form.
Answer: log₁₀ 10 = 1
ax = y means logₐ y = x.
4.Evaluate log₂ 16.
Answer: 4
24 = 16
5.Evaluate log₁₀ 1000.
Answer: 3
103 = 1000
6.Evaluate log₂ 128.
Answer: 7
27 = 128
7.Write 53 = 125 in logarithm form.
Answer: log₅ 125 = 3
ax = y means logₐ y = x.
8.Evaluate log₃ 3.
Answer: 1
31 = 3
9.Evaluate log₂ 32.
Answer: 5
25 = 32
10.Write 26 = 64 in logarithm form.
Answer: log₂ 64 = 6
ax = y means logₐ y = x.
11.Evaluate log₃ 9.
Answer: 2
32 = 9
12.Write 32 = 9 in logarithm form.
Answer: log₃ 9 = 2
ax = y means logₐ y = x.
Marking tips
- Give credit for correct method even when the final answer slips — the working shows where the thinking went right.
- For open-ended tasks, use the success criteria as a checklist rather than looking for one "right" answer.
- Celebrate what went well first, then pick one thing to work on next.
Great work. Here's what to try next:
