If you have something in the form \(\sqrt{-a}\) for some \(a > 0\), then we can break it up using exponent / radical properties: \(\sqrt{-a} = \sqrt{-1 \times a} = \sqrt{-1} \sqrt{a} = i \sqrt{a} \)

so it would be i\[\sqrt{16}\]?

\(i \sqrt{16}\) Yes, although we can go a step further since \(\sqrt{16}\) is the square root of a perfect square. = \(4i\)
