\[
\sqrt{-7} = i\sqrt{7}
\]
Solución
To express \(\sqrt{-7}\) in terms of the imaginary unit \(i\), where \(i = \sqrt{-1}\), follow these steps:
\[
\sqrt{-7} = \sqrt{7} \times \sqrt{-1} = \sqrt{7} \times i = i\sqrt{7}
\]
**Final Answer:**
\[
\sqrt{-7} = i\,\sqrt{7}
\]

Simplifique esta solución Beyond the Answer
To express \( \sqrt{-7} \) in terms of \( i \), we start by recalling that \( i \) is the imaginary unit defined as \( i = \sqrt{-1} \). Thus, we can rewrite \( \sqrt{-7} \) as follows: \[ \sqrt{-7} = \sqrt{7} \cdot \sqrt{-1} = \sqrt{7} \cdot i \] So, the simplified form of \( \sqrt{-7} \) in terms of \( i \) is: \[ \sqrt{-7} = i\sqrt{7} \]
