Lesson of the week
Logarithms
From the study guide Logarithms of products
Study guide for Grades 10 to 12: 2 worked examples and 2 practice questions. For real logarithms: b > 0, b ≠ 1, u > 0 and v > 0.
- log_b(uv) = log_b(u) + log_b(v)
- For real logarithms: b > 0, b ≠ 1, u > 0 and v > 0.
- Example: Evaluate log base 4 of (1024 × 64). Answer: 8.
