1. **State the problem:** Solve the inequality $$49 \cdot \left(\frac{1}{8}\right)^{-2x-6} > \left(\frac{1}{32}\right)^{-x+11}$$.
2. **Rewrite bases as powers of primes:**
- $49 = 7^2$
- $\frac{1}{8} = 8^{-1} = 2^{-3}$
- $\frac{1}{32} = 32^{-1} = 2^{-5}$
3. **Rewrite the inequality using these bases:**
$$7^2 \cdot \left(2^{-3}\right)^{-2x-6} > \left(2^{-5}\right)^{-x+11}$$
4. **Simplify exponents:**
$$7^2 \cdot 2^{3(2x+6)} > 2^{5(x-11)}$$
5. **Rewrite:**
$$7^2 \cdot 2^{6x+18} > 2^{5x - 55}$$
6. **Divide both sides by $2^{5x - 55}$:**
$$7^2 \cdot \frac{2^{6x+18}}{2^{5x - 55}} > 1$$
7. **Use exponent subtraction:**
$$7^2 \cdot 2^{(6x+18) - (5x - 55)} > 1$$
8. **Simplify exponent:**
$$7^2 \cdot 2^{x + 73} > 1$$
9. **Rewrite $7^2$ as $49$:**
$$49 \cdot 2^{x + 73} > 1$$
10. **Divide both sides by 49:**
$$\cancel{49} \cdot 2^{x + 73} > \frac{1}{\cancel{49}}$$
$$2^{x + 73} > \frac{1}{49}$$
11. **Rewrite $\frac{1}{49} = 49^{-1} = 7^{-2}$, but better to take log base 2:**
12. **Take logarithm base 2 of both sides:**
$$x + 73 > \log_2\left(\frac{1}{49}\right) = -\log_2(49)$$
13. **Calculate $\log_2(49)$:**
$$49 = 7^2 \Rightarrow \log_2(49) = 2 \log_2(7)$$
14. **Final inequality:**
$$x + 73 > -2 \log_2(7)$$
15. **Solve for $x$:**
$$x > -73 - 2 \log_2(7)$$
---
**Final answer:**
$$\boxed{x > -73 - 2 \log_2(7)}$$
