Answer
If $p$, then $q$.
$p$.
Therefore, $q$.
If all algebraic expressions can be written in prefix notation, then $(a+2b)(a^{2}-b)$ can be written in prefix notation.
All algebraic expressions can be written in prefix notation.
Therefore, $(a+2b)(a^{2}-b)$ can be written in prefix notation.
Work Step by Step
Replace each complete idea (i.e., an idea that can be expressed as a complete, independent sentence) as a single letter (here, $p$ or $q$). Fill in the blanks in the example argument based on where you put the letters $p$ and $q$ by examining the first argument. Note that you do not need to know what prefix notation is to understand the argument.
