p (2) = 2^{3} - 2

$p (2) = 2^{3} - 2$

Step 1

Divide each term in

p (2) = 2^{3} - 2

$p (2) = 2^{3} - 2$ by

2

$2$ .

\frac{p \cdot 2}{2} = \frac{2^{3}}{2} + \frac{- 2}{2}

$\frac{p \cdot 2}{2} = \frac{2^{3}}{2} + \frac{- 2}{2}$

Step 3.2.1

Raise

$2$ to the power of

$3$ .

$p = \frac{8 - 2}{2}$

Step 3.2.2

Subtract

$2$ from

$8$ .
