| Topic | Chain Rule |
| Type | Basic power rule differentiation |
| Difficulty | Easy -1.2 This is a straightforward differentiation question requiring only basic power rule application after rewriting terms as powers (x^{1/2} and 3x^{-1}). It's a single-step, routine C2 exercise with no chain rule despite the topic label, making it easier than average A-level questions. |
