Answer 1

Answer:

$3i\sqrt2$

Step-by-step explanation:

We can rewrite the square root of negative 18 as $\sqrt{18} \cdot\sqrt{-1}$. We can evaluate these two quantities separately. The square root of 18 can be factored to get 3 squared times 2. We can take the 3 out to get $3\sqrt2$. Now, the square root of negative one can be rewritten as $i$, so this is equal to $3i\sqrt2$
