Solve for s5 s_5=(4(1-2^5))/(1-2)

$s_{5} = \frac{4 (1 - 2^{5})}{1 - 2}$

Step 1

Simplify the numerator.

Raise $2$ to the power of $5$ .

$s_{5} = \frac{4 (1 - 1 \cdot 32)}{1 - 2}$

Multiply $- 1$ by $32$ .

$s_{5} = \frac{4 (1 - 32)}{1 - 2}$

Subtract $32$ from $1$ .

$s_{5} = \frac{4 \cdot - 31}{1 - 2}$

$s_{5} = \frac{4 \cdot - 31}{1 - 2}$

Step 2

Simplify the expression.

Subtract $2$ from $1$ .

$s_{5} = \frac{4 \cdot - 31}{- 1}$

Multiply $4$ by $- 31$ .

$s_{5} = \frac{- 124}{- 1}$

Divide $- 124$ by $- 1$ .

$s_{5} = 124$

$s_{5} = 124$
