Answer 1

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 \(\log_4 64\).**
