Identify the logarithmic property that allows you to combine the sum of two logarithms with the same base into a single logarithm. This property is: \(\log_b A + \log_b B = \log_b (A \times B)\).
Apply the property to the given expression \(\log_3 4 + \log_3 9\) by multiplying the arguments inside a single logarithm: \(\log_3 (4 \times 9)\).
Calculate the product inside the logarithm without simplifying the logarithm itself: \(4 \times 9 = 36\), so the expression becomes \(\log_3 36\).
Check if the argument 36 can be simplified further by expressing it as a power of the base 3 or a product of powers of 3. Since \(36 = 3^2 \times 4\), and 4 is not a power of 3, the expression cannot be simplified further using logarithm properties.
Conclude that the sum \(\log_3 4 + \log_3 9\) is rewritten as the single logarithm \(\log_3 36\), which is the simplified form.
