Step 2.1

Raise $i$ to the power of $1$ .

$\frac{s (i^{1} i) m p l f y \cdot 2}{15}$

Step 2.2

Raise $i$ to the power of $1$ .

$\frac{s (i^{1} i^{1}) m p l f y \cdot 2}{15}$

Step 2.3

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\frac{s i^{1 + 1} m p l f y \cdot 2}{15}$

Step 2.4

Add $1$ and $1$ .

$\frac{s i^{2} m p l f y \cdot 2}{15}$

Step 3

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

$\frac{s \cdot - 1 m p l f y \cdot 2}{15}$

Step 4

Multiply $2$ by $- 1$ .

$\frac{s \cdot - 2 m p l f y}{15}$

Step 5

Move $- 2$ to the left of $s$ .

$\frac{- 2 \cdot s m p l f y}{15}$

Step 6

Move the negative in front of the fraction.

$- \frac{2 s m p l f y}{15}$
