$- 5 + 2 i \sqrt{6} + 1 + i \cdot \sqrt{3^{2} \cdot 6}$

Step 1.17

Pull terms out from under the radical.

$- 5 + 2 i \sqrt{6} + 1 + i \cdot (| 3 | \sqrt{6})$

Step 1.18

The absolute value is the distance between a number and zero. The distance between $0$ and $3$ is $3$ .

$- 5 + 2 i \sqrt{6} + 1 + i \cdot (3 \sqrt{6})$

Step 1.19

Move $3$ to the left of $i$ .

$- 5 + 2 i \sqrt{6} + 1 + 3 i \sqrt{6}$

Step 2
