| Topic | Indices and Surds |
| Type | Expand and simplify surd expressions |
| Difficulty | Easy -1.2 This is a straightforward C1 question testing basic surd manipulation skills. Part (i) requires routine expansion using FOIL and collecting like terms, while part (ii) involves simplifying surds and rationalizing denominators—both are standard textbook exercises requiring only procedural recall with no problem-solving or insight needed. |
| Spec | 1.02b Surds: manipulation and rationalising denominators |
4 (i) Expand and simplify $( 7 + 3 \sqrt { 2 } ) ( 5 - 2 \sqrt { 2 } )$.\\
(ii) Simplify $\sqrt { 54 } + \frac { 12 } { \sqrt { 6 } }$.
