<reasoning>

Identify the summation parameters

\[

$$\begin{aligned} &\text{Expression: } \sum_{k=1}^{6} k^9 \\ &\text{Lower limit: } k = 1 \\ &\text{Upper limit: } k = 6 \\ &\text{General term: } a_k = k^9 \end{aligned}$$

\]

Generate the terms of the sum

\[

$$\begin{aligned} &k = 1 \implies 1^9 \\ &k = 2 \implies 2^9 \\ &k = 3 \implies 3^9 \\ &k = 4 \implies 4^9 \\ &k = 5 \implies 5^9 \\ &k = 6 \implies 6^9 \end{aligned}$$

\]

Write the expanded sum

\[
1^9 + 2^9 + 3^9 + 4^9 + 5^9 + 6^9
\]
