To combine the expression \( \log_3 z + \log_3 2 + \log_3 4 \) into a single logarithm, we can use the logarithmic property that states \( \log_b x + \log_b y = \log_b (xy) \).

Let’s apply this property step by step:

  1. Combine \( \log_3 z \) and \( \log_3 2 \): \[ \log_3 z + \log_3 2 = \log_3 (2z) \]

  2. Now, add \( \log_3 4 \) to \( \log_3 (2z) \): \[ \log_3 (2z) + \log_3 4 = \log_3 (2z \cdot 4) \]

  3. Simplify \( 2z \cdot 4 \): \[ 2z \cdot 4 = 8z \]

Putting it all together, we have: \[ \log_3 z + \log_3 2 + \log_3 4 = \log_3 (8z) \]

Therefore, the final expression as a single logarithm is: \[ \log_3(8z) \]

So the correct response is: log3(8z)
