1. **Stating the problem:** We are given an expression involving logarithms with base 7: $$\log_7 174 = 7 \log_7 174 + 7 \log_7 174$$ and need to analyze or simplify it.
2. **Recall logarithm properties:**
- The logarithm of a product: $$\log_b (xy) = \log_b x + \log_b y$$
- The logarithm of a power: $$\log_b (x^k) = k \log_b x$$
3. **Analyze the given equation:**
$$\log_7 174 = 7 \log_7 174 + 7 \log_7 174$$
4. **Combine the right side:**
$$7 \log_7 174 + 7 \log_7 174 = 14 \log_7 174$$
5. **Rewrite the equation:**
$$\log_7 174 = 14 \log_7 174$$
6. **Subtract $$\log_7 174$$ from both sides:**
$$\log_7 174 - 14 \log_7 174 = 0$$
7. **Factor out $$\log_7 174$$:**
$$\cancel{\log_7 174} (1 - 14) = 0$$
8. **Simplify:**
$$\log_7 174 \times (-13) = 0$$
9. **Since $$-13 \neq 0$$, for the product to be zero:**
$$\log_7 174 = 0$$
10. **Check if $$\log_7 174 = 0$$ is true:**
By definition, $$\log_7 174 = 0$$ means $$7^0 = 174$$ which is $$1 = 174$$, which is false.
**Conclusion:** The given equation is not true for any real value; it is a contradiction.
**Final answer:** The equation $$\log_7 174 = 7 \log_7 174 + 7 \log_7 174$$ is false and has no solution.
