Identify the given expression: \(3\log_4 a - \frac{1}{2} \log_4 (b+1) + \log_4 (4c)\).
Apply the logarithm power rule to move coefficients as exponents inside the logs: rewrite as \(\log_4 (a^3) - \log_4 ((b+1)^{\frac{1}{2}}) + \log_4 (4c)\).
Recognize that \(\log_4 ((b+1)^{\frac{1}{2}})\) is the same as \(\log_4 \sqrt{b+1}\), so the expression becomes \(\log_4 (a^3) - \log_4 \sqrt{b+1} + \log_4 (4c)\).
Use the logarithm subtraction and addition rules: \(\log_b M - \log_b N = \log_b \left(\frac{M}{N}\right)\) and \(\log_b M + \log_b N = \log_b (MN)\) to combine the terms into a single logarithm.
Combine all terms into one log expression: \(\log_4 \left( \frac{4 a^3 c}{\sqrt{b+1}} \right)\).
