| Topic | Indices and Surds |
| Type | Simplify algebraic expressions with indices |
| Difficulty | Easy -1.3 This is a straightforward indices and surds question requiring only direct application of basic index laws (√x = x^(1/2), multiplication adds powers, power of a power multiplies). Both parts are routine drill exercises with no problem-solving element, making it easier than average A-level content. |
