$(i \sqrt{- 36}) (\sqrt{- 200})$

Step 1

Rewrite $- 36$ as $- 1 (36)$ .

$i \sqrt{- 1 (36)} \sqrt{- 200}$

Step 2

Rewrite $\sqrt{- 1 (36)}$ as $\sqrt{- 1} \cdot \sqrt{36}$ .

$i (\sqrt{- 1} \cdot \sqrt{36}) \sqrt{- 200}$

Step 3

Rewrite $\sqrt{- 1}$ as $i$ .

$i (i \cdot \sqrt{36}) \sqrt{- 200}$

Step 4

Rewrite $- 200$ as $- 1 (200)$ .

$i (i \cdot \sqrt{36}) \sqrt{- 1 (200)}$

Step 5

Rewrite $\sqrt{- 1 (200)}$ as $\sqrt{- 1} \cdot \sqrt{200}$ .

$i (i \cdot \sqrt{36}) (\sqrt{- 1} \cdot \sqrt{200})$

Step 6

Rewrite $\sqrt{- 1}$ as $i$ .

$i (i \cdot \sqrt{36}) (i \cdot \sqrt{200})$

Step 7

Rewrite $36$ as $6^{2}$ .

$i (i \cdot \sqrt{6^{2}}) (i \cdot \sqrt{200})$

Step 8

Pull terms out from under the radical, assuming positive real numbers.

$i (i \cdot 6) (i \cdot \sqrt{200})$

Step 9
