Step 1.1.1

Multiply $6$ by $- 3$ .

$- 18 i i - 3 (- 7 + 6 i)$

Step 1.1.2

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

$- 18 (i^{1} i) - 3 (- 7 + 6 i)$

Step 1.1.3

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

$- 18 (i^{1} i^{1}) - 3 (- 7 + 6 i)$

Step 1.1.4

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

$- 18 i^{1 + 1} - 3 (- 7 + 6 i)$

Step 1.1.5

Add $1$ and $1$ .

$- 18 i^{2} - 3 (- 7 + 6 i)$

$- 18 i^{2} - 3 (- 7 + 6 i)$

Step 1.2

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

$- 18 \cdot - 1 - 3 (- 7 + 6 i)$

Step 1.3

Multiply $- 18$ by $- 1$ .

$18 - 3 (- 7 + 6 i)$

Step 1.4

Apply the distributive property.

$18 - 3 \cdot - 7 - 3 (6 i)$

Step 1.5

Multiply $- 3$ by $- 7$ .

$18 + 21 - 3 (6 i)$

Step 1.6

Multiply $6$ by $- 3$ .

$18 + 21 - 18 i$

$18 + 21 - 18 i$

Step 2

Add $18$ and $21$ .

$39 - 18 i$
