<reasoning>

Separate the negative sign

Using the Imaginary Numbers knowledge point
\[
\sqrt{-45} = \sqrt{-1 \cdot 45} = \sqrt{-1} \cdot \sqrt{45} = i\sqrt{45}
\]

Simplify the radical

Using the Product Rule for Radicals knowledge point
\[
\sqrt{45} = \sqrt{9 \cdot 5} = \sqrt{9} \cdot \sqrt{5} = 3\sqrt{5}
\]

Combine the results

Using the Imaginary Numbers and Product Rule for Radicals knowledge points
\[
\sqrt{-45} = 3i\sqrt{5}
\]
</reasoning>

<answer>
Express the number in terms of \(i\).

\(\sqrt{-45} =\) <blank>\(3i\sqrt{5}\)</blank>
