$v \cdot w \cdot y \cdot u \cdot v$

Explanation:

Step1: Identify like variables

The expression has two instances of $v$, and one each of $w$, $y$, $u$.

Step2: Combine like variables via exponents

When multiplying identical variables, add their exponents: $v \cdot v = v^{1+1} = v^2$.

Step3: Write simplified expression

Combine all terms, ordering variables alphabetically for clarity.

Answer:

$u v^2 w y$
