Question: Using an appropriate property of logarithms, $3 \cdot \log_5 4$ can be expressed as which single logarithm?
1. **State the problem:** We want to express $3 \cdot \log_5 4$ as a single logarithm.
2. **Recall the logarithm power rule:** The property $a \cdot \log_b c = \log_b (c^a)$ allows us to rewrite the product of a constant and a logarithm as a single logarithm with the argument raised to that constant.
3. **Apply the property:**
$$3 \cdot \log_5 4 = \log_5 (4^3)$$
4. **Calculate the power:**
$$4^3 = 4 \times 4 \times 4 = 64$$
5. **Final expression:**
$$3 \cdot \log_5 4 = \log_5 64$$
**Answer:** $\log_5 64$
