$- 8 x i - 3 y i^{3}$

Step 1

Factor out $i^{2}$ .

$- 8 x i - 3 y (i^{2} \cdot i)$

Step 2

Rewrite $i^{2}$ as $- 1$ .

$- 8 x i - 3 y (- 1 \cdot i)$

Step 3

Rewrite $- 1 i$ as $- i$ .

$- 8 x i - 3 y (- i)$

Step 4

Multiply $- 1$ by $- 3$ .

$- 8 x i + 3 y i$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
