**Mathematical Computation Exercise**

**Objective:** Compute the given product expression.

**Expression:** 
\[
\prod_{k=5}^{5} \left( 1 - \frac{1}{k} \right) = 1 - \frac{1}{5}
\]

**Explanation:**

- The symbol \(\prod\) denotes a product similar to a summation, but for multiplication.
- The limits of the product are from \(k = 5\) to \(k = 5\). This implies that there is only one term in the sequence.
- The expression inside the product is:
  \[
  1 - \frac{1}{k}
  \]
  When \(k = 5\), this simplifies to:
  \[
  1 - \frac{1}{5} = \frac{5}{5} - \frac{1}{5} = \frac{4}{5}
  \]

**Solution:**

The result of the computation is:
\[
\frac{4}{5}
\] 

This exercise demonstrates the evaluation of a simple product involving a single term. In cases where \(k\) ranges over more values, the process would involve multiplying all terms for \(k\) within the specified range.
