Solve for S4 S_4=3(1-(-2)^4)

$S_{4} = 3 (1 - {(- 2)}^{4})$

Step 1

Simplify each term.

Raise $- 2$ to the power of $4$ .

$S_{4} = 3 (1 - 1 \cdot 16)$

Multiply $- 1$ by $16$ .

$S_{4} = 3 (1 - 16)$

$S_{4} = 3 (1 - 16)$

Step 2

Simplify the expression.

Subtract $16$ from $1$ .

$S_{4} = 3 \cdot - 15$

Multiply $3$ by $- 15$ .
