Solve for S6 S_6=(5(1-2^6))/(1-2)

$S_{6} = \frac{5 (1 - 2^{6})}{1 - 2}$

Step 1

Simplify the numerator.

Raise $2$ to the power of $6$ .

$S_{6} = \frac{5 (1 - 1 \cdot 64)}{1 - 2}$

Multiply $- 1$ by $64$ .

$S_{6} = \frac{5 (1 - 64)}{1 - 2}$

Subtract $64$ from $1$ .

$S_{6} = \frac{5 \cdot - 63}{1 - 2}$

$S_{6} = \frac{5 \cdot - 63}{1 - 2}$

Step 2

Simplify the expression.

Subtract $2$ from $1$ .

$S_{6} = \frac{5 \cdot - 63}{- 1}$

Multiply $5$ by $- 63$ .

$S_{6} = \frac{- 315}{- 1}$

Divide $- 315$ by $- 1$ .

$S_{6} = 315$

$S_{6} = 315$
