To show that the Product Rule of Logarithms works for the base 4 expression \(\log_4 16 + \log_4 4\), we need to evaluate both logarithms and demonstrate that their sum is equal to the logarithm of the product of their arguments.

Given:

  • \(\log_4 16\)
  • \(\log_4 4\)

We can evaluate these:

  1. \(\log_4 16\): Since \(16 = 4^2\), we have \(\log_4 16 = 2\).
  2. \(\log_4 4\): Since \(4 = 4^1\), we find \(\log_4 4 = 1\).

Now, adding these results: \[ \log_4 16 + \log_4 4 = 2 + 1 = 3. \]

Now, we need to check the value of \(\log_4(16 \times 4)\): \[ 16 \times 4 = 64, \] and since \(64 = 4^3\), we have \(\log_4 64 = 3\).

Thus, we find that: \[ \log_4 16 + \log_4 4 = \log_4 64. \]

The best response that describes this conclusion is: Evaluate both \(\log_4 16\) and \(\log_4 4\) and show that their sum is equal to the value of \(\log_4 64\).
