The image you uploaded contains a mathematical expression. Here is the expression as interpreted from the image:

\[
\sum_{k=1}^{\infty} \frac{n! \cdot k \cdot (x+1)^k}{k!} = x + \frac{1}{2}x^2 + \frac{1}{3}x^3 + \ldots + \frac{1}{n}x^n
\]

If this interpretation is correct, the expression on the left-hand side appears to be an infinite series, and the right-hand side shows a finite sum involving powers of \(x\).

Would you like a detailed explanation or a solution for this expression? If you want me to check for a specific property, simplification, or application, let me know!
