$(- 2 r^{2} s^{0}) {(r s^{4})}^{2}$

Step 1

Anything raised to $0$ is $1$ .

$- 2 r^{2} \cdot 1 {(r s^{4})}^{2}$

Step 2

Multiply $- 2$ by $1$ .

$- 2 r^{2} {(r s^{4})}^{2}$

Step 3

Apply the product rule to $r s^{4}$ .

$- 2 r^{2} (r^{2} {(s^{4})}^{2})$

Step 4

Multiply $r^{2}$ by $r^{2}$ by adding the exponents.
