| Type | Evaluate numerical powers |
| Difficulty | Easy -1.3 This is a straightforward C1 indices question testing basic recall and application of index laws. Part (i) requires simple manipulation of negative and fractional powers with no problem-solving. Part (ii) involves routine algebraic simplification using standard index rules. Both parts are mechanical exercises below average A-level difficulty. |
