| Topic | Indices and Surds |
| Type | Simplify algebraic expressions with indices |
| Difficulty | Easy -1.3 This is a straightforward C1 indices question requiring direct application of index laws with no problem-solving. Part (a) is routine evaluation of a fractional power, and part (b) is mechanical simplification using negative and fractional index rules. Both parts are standard textbook exercises testing basic recall and technique. |
