| Topic | Indices and Surds |
| Type | Simplify algebraic expressions with indices |
| Difficulty | Easy -1.8 This is a straightforward indices question testing basic recall of negative and fractional powers. Part (i) requires simple application of negative index rule, and part (ii) is routine simplification using fractional indices. Both are standard textbook exercises with no problem-solving element, making this significantly easier than average A-level questions. |
