| Topic | Indices and Surds |
| Type | Simplify algebraic expressions with indices |
| Difficulty | Easy -1.3 This is a straightforward C1 question testing basic index law recall and manipulation. Part (i) requires simple evaluation of a negative fractional power, and part (ii) involves routine application of index laws to simplify an algebraic fraction. Both parts are standard textbook exercises with no problem-solving or conceptual challenge beyond remembering the rules. |

2 (i) Evaluate $9 ^ { - \frac { 1 } { 2 } }$.\\
(ii) Simplify $\frac { \left( 4 x ^ { 4 } \right) ^ { 3 } y ^ { 2 } } { 2 x ^ { 2 } y ^ { 5 } }$.
