Step 2.2.1

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

$\frac{1}{2} \cdot 25 - \frac{1}{2} \cdot 0^{2}$

Step 2.2.2

Combine $\frac{1}{2}$ and $25$ .

$\frac{25}{2} - \frac{1}{2} \cdot 0^{2}$

Step 2.2.3

Raising $0$ to any positive power yields $0$ .

$\frac{25}{2} - \frac{1}{2} \cdot 0$

Step 2.2.4

Multiply $0$ by $- 1$ .

$\frac{25}{2} + 0 (\frac{1}{2})$

Step 2.2.5

Multiply $0$ by $\frac{1}{2}$ .

$\frac{25}{2} + 0$

Step 2.2.6

Add $\frac{25}{2}$ and $0$ .

$\frac{25}{2}$

Step 3

The result can be shown in multiple forms.
