| Topic | Indices and Surds |
| Type | Expand and simplify surd expressions |
| Difficulty | Easy -1.3 This is a straightforward two-part question testing basic surd manipulation skills. Part (i) requires simplifying square roots and canceling (routine technique), while part (ii) is a standard expansion using $(a-b)^2$ with minimal algebraic complexity. Both are textbook exercises requiring only recall and careful arithmetic, making this easier than average for A-level. |
