## How do students think about us  ## Solving Logarithmic Functions – Explanation & Examples

log 2 x - log 2 5 = 2 + log 2 3. Solution : log 2 x - log 2 5 = 2 + log 2 3. Use the fundamental law of logarithm. log 2 (x/5) = 2 + log 2 3. Subtract log 2 3 from each side. log 2 (x/5) - log 2 3 = 2. log
