| Type | Rationalize denominator simple |
| Difficulty | Easy -1.2 This is a straightforward application of rationalizing the denominator by multiplying by the conjugate (3 + √5)/(3 + √5), requiring only basic algebraic manipulation and knowledge of difference of two squares. It's a standard textbook exercise with a single technique and no problem-solving required, making it easier than average. |

I don't see any mark scheme content to clean up in your message. You've provided "Question 1:" followed by "1", but there's no actual marking scheme text with annotations (M1, A1, B1, etc) or unicode symbols to convert.
Please provide the extracted mark scheme content you'd like me to clean up, and I'll convert it to the format you've requested.1 Write $\frac { 8 } { 3 - \sqrt { 5 } }$ in the form $a + b \sqrt { 5 }$, where $a$ and $b$ are integers to be found.
