Step 1.1

Raise

i

$i$ to the power of

1

$1$ .

7 (i^{1} i)

$7 (i^{1} i)$

Step 1.2

Raise

i

$i$ to the power of

1

$1$ .

7 (i^{1} i^{1})

$7 (i^{1} i^{1})$

Step 1.3

Use the power rule

a^{m} a^{n} = a^{m + n}

$a^{m} a^{n} = a^{m + n}$ to combine exponents.

7 i^{1 + 1}

$7 i^{1 + 1}$

Step 1.4

Add

1

$1$ and

1

$1$ .

7 i^{2}

$7 i^{2}$

7 i^{2}

$7 i^{2}$

Step 2

Rewrite

i^{2}

$i^{2}$ as

- 1

$- 1$ .

7 \cdot - 1

$7 \cdot - 1$

Step 3

Multiply

7

$7$ by

- 1

$- 1$ .

- 7

$- 7$
