Identify the logarithmic expression given: \(\log_4(4x)\), which is the logarithm base 4 of the product \$4x$.
Recall the logarithm product rule: \(\log_b(MN) = \log_b(M) + \log_b(N)\). Apply this rule to split the log of the product into a sum of logs: \(\log_4(4x) = \log_4(4) + \log_4(x)\).
Evaluate \(\log_4(4)\) by recognizing that since the base and the argument are the same, \(\log_4(4) = 1\) because \$4^1 = 4$.
Substitute the value back into the expression to get \(1 + \log_4(x)\).
Check if further simplification is possible. Since \(\log_4(x)\) cannot be simplified without additional information about \(x\), the expression \(1 + \log_4(x)\) is the simplified sum of logarithms.
