    \(\sqrt{-200}=i\sqrt{200}=i10\sqrt{2}\)

    hint: we can write this: \[\Large - 200 = 200\left\{ {\cos \left( {\pi + 2k\pi } \right) + i\sin \left( {\pi + 2k\pi } \right)} \right\}\]

    how did root (96) simplify to 4?

    we have two square roots: \[\Large \begin{gathered} \sqrt { - 200} = \sqrt {200} \left\{ {\cos \left( {\frac{\pi }{2} + k\pi } \right) + i\sin \left( {\frac{\pi }{2} + k\pi } \right)} \right\}, \hfill \\ \hfill \\ k = 0,1 \hfill \\ \end{gathered} \]

    root(96)=root(16x6)=4root(6)
