Question: Sydney has 196 pepper plants that she wants to plant in square formation. How many pepper plants should she plant in each row?
1. **State the problem:** Sydney has $196$ pepper plants and wants to arrange them in a square formation. We need to find how many plants go in each row.
2. **Formula used:** For a square formation, the total number of plants is the square of the number of plants per row. If $x$ is the number of plants per row, then:
$$x^2 = 196$$
3. **Solve for $x$:**
Take the square root of both sides:
$$x = \sqrt{196}$$
4. **Calculate the square root:**
$$x = 14$$
5. **Interpretation:** Sydney should plant $14$ pepper plants in each row to form a perfect square.
**Final answer:** $14$ plants per row.
