Identify the Variable

1. In the expression $3f^5 + 73$, we need to determine which part represents the variable.
2. The expression consists of two terms: $3f^5$ and $73$.

Relevant Concepts

1. A variable is a symbol used to represent an unknown value. In algebra, variables are typically represented by letters such as $f$ in this case.

Analysis and Detail

1. In the term $3f^5$, $f$ is raised to the fifth power, indicating that $f$ is the variable, while $3$ is a coefficient.
2. The term $73$ is simply a constant; it does not contain any variable.

Verify and Summarize

1. The only element that can change and is represented by a letter in this expression is $f$.
2. The constant $73$ does not qualify as a variable.

Final Answer

The variable is $f$.
