Summation Equation 5D5Bc6
1. The problem is to analyze the summation $$\sum_{i=1}^n iL(2)^{x+2} = (n-2)^{x+2} A$$ with the condition $$n > 0$$.
2. First, understand the summation notation: $$\sum_{i=1}^n iL(2)^{x+2}$$ means adding the terms $$iL(2)^{x+2}$$ for $$i$$ from 1 to $$n$$.
3. Since $$L(2)^{x+2}$$ does not depend on $$i$$, it can be factored out:
$$\sum_{i=1}^n iL(2)^{x+2} = L(2)^{x+2} \sum_{i=1}^n i$$
4. The sum of the first $$n$$ natural numbers is:
$$\sum_{i=1}^n i = \frac{n(n+1)}{2}$$
5. Substitute this back:
$$L(2)^{x+2} \cdot \frac{n(n+1)}{2} = (n-2)^{x+2} A$$
6. This equation relates $$n$$, $$x$$, $$L$$, and $$A$$. To solve for $$A$$:
$$A = \frac{L(2)^{x+2} \cdot \frac{n(n+1)}{2}}{(n-2)^{x+2}} = \frac{L(2)^{x+2} n(n+1)}{2 (n-2)^{x+2}}$$
7. Important notes:
- $$n > 0$$ and $$n \neq 2$$ to avoid division by zero.
- $$L$$ and $$A$$ are constants or parameters depending on context.
Final answer:
$$A = \frac{L(2)^{x+2} n(n+1)}{2 (n-2)^{x+2}}$$
