Step 2.1

Subtract $5$ from $2$ .

$4 + {(- 3)}^{2} - 4 {(7 - 5)}^{3} + 2 (\frac{15}{3}) - \sqrt{16}$

Step 2.2

Raise $- 3$ to the power of $2$ .

$4 + 9 - 4 {(7 - 5)}^{3} + 2 (\frac{15}{3}) - \sqrt{16}$

Step 2.3

Subtract $5$ from $7$ .

$4 + 9 - 4 \cdot 2^{3} + 2 (\frac{15}{3}) - \sqrt{16}$

Step 2.4

Raise $2$ to the power of $3$ .

$4 + 9 - 4 \cdot 8 + 2 (\frac{15}{3}) - \sqrt{16}$

Step 2.5

Multiply $- 4$ by $8$ .

$4 + 9 - 32 + 2 (\frac{15}{3}) - \sqrt{16}$

Step 2.6

Divide $15$ by $3$ .
