$a_{3} = - 1 {(\frac{1}{3})}^{3 - 1}$

Step 1

Subtract $1$ from $3$ .

$a_{3} = - 1 {(\frac{1}{3})}^{2}$

Step 2

Apply the product rule to $\frac{1}{3}$ .

$a_{3} = - 1 \frac{1^{2}}{3^{2}}$

Step 3

One to any power is one.

$a_{3} = - 1 \frac{1}{3^{2}}$

Step 4

Raise $3$ to the power of $2$ .

$a_{3} = - 1 (\frac{1}{9})$

Step 5

Rewrite $- 1 (\frac{1}{9})$ as $- (\frac{1}{9})$ .

$a_{3} = - \frac{1}{9}$

Step 6

The result can be shown in multiple forms.

Exact Form:

$a_{3} = - \frac{1}{9}$

Decimal Form:

$a_{3} = - 0.\overline{1}$
