4 \sqrt{2} i

Step-by-step explanation:

We want to find the sum of

\sqrt{ - 2} + \sqrt{ - 18}

We can rewrite this as

\sqrt{ 2 \times - 1} + \sqrt{ 18 \times - 1}

This becomes;

\sqrt{2} \times \sqrt{ - 1} + \sqrt{18} \times \sqrt{ - 1}

Recall that;

i = \sqrt{ - 1}

This implies that;

\sqrt{2} i + 3 \sqrt{2} i

Combine like terms:

4 \sqrt{2} i
