| Topic | Indices and Surds |
| Type | Simplify algebraic expressions with indices |
| Difficulty | Easy -1.8 This is a very basic algebraic manipulation question testing only the most fundamental index laws (division of powers and negative indices). Each part is a single-step simplification requiring only recall of basic rules, with no problem-solving element whatsoever. This is significantly easier than typical A-level questions. |
| Spec | 1.02a Indices: laws of indices for rational exponents |
Simplify fully the following expressions:
\begin{enumerate}[label=(\roman*)]
\item $\frac{7y^{13}}{35y^7}$ [1]
\item $6x^{-2} \div x^{-5}$ [1]
\end{enumerate}
