| Type | Evaluate numerical powers |
| Difficulty | Easy -1.8 This is a very basic indices question testing only fundamental recall of index laws (a^m × a^n = a^(m+n) and fractional powers). Both parts are single-step calculations with no problem-solving required, making it significantly easier than average A-level content. |
| Spec | 1.02a Indices: laws of indices for rational exponents |
Find the value of each of the following.
\begin{enumerate}[label=(\roman*)]
\item $5^2 \times 5^{-2}$ [2]
\item $100^{\frac{1}{2}}$ [1]
\end{enumerate}
