Solve for s6 s_6=(125(1-1.25^6))/(1-1.25)

$s_{6} = \frac{125 (1 - {1.25}^{6})}{1 - 1.25}$

Step 1

Simplify the numerator.

Raise $1.25$ to the power of $6$ .

$s_{6} = \frac{125 (1 - 1 \cdot 3.81469726)}{1 - 1.25}$

Multiply $- 1$ by $3.81469726$ .

$s_{6} = \frac{125 (1 - 3.81469726)}{1 - 1.25}$

Subtract $3.81469726$ from $1$ .

$s_{6} = \frac{125 \cdot - 2.81469726}{1 - 1.25}$

Step 2

Simplify the expression.

Subtract $1.25$ from $1$ .

$s_{6} = \frac{125 \cdot - 2.81469726}{- 0.25}$

Multiply $125$ by $- 2.81469726$ .

$s_{6} = \frac{- 351.8371582}{- 0.25}$

Divide $- 351.8371582$ by $- 0.25$ .

$s_{6} = 1407.34863281$
