Step 1.1

Rewrite $i^{4}$ as ${(i^{2})}^{2}$ .

$- 6 y i - 9 x {(i^{2})}^{2}$

Step 1.2

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

$- 6 y i - 9 x {(- 1)}^{2}$

Step 1.3

Raise $- 1$ to the power of $2$ .

$- 6 y i - 9 x \cdot 1$

$- 6 y i - 9 x \cdot 1$

Step 2

Multiply $- 9$ by $1$ .

$- 6 y i - 9 x$

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