Step 1.1

Add $1$ and $1$ .

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

Step 1.2

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

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

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

Step 2

Simplify the denominator.

Step 2.1

Evaluate the exponent.

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

Step 2.2

Subtract $1$ from $2$ .

$a_{1} = \frac{1}{1}$
