$\frac{- 5^{0}}{2^{- 2}}$

Step 1

Move $2^{- 2}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$- 5^{0} \cdot 2^{2}$

Step 2

Anything raised to $0$ is $1$ .

$- 1 \cdot 1 \cdot 2^{2}$

Step 3

Multiply $- 1$ by $1$ .

$- 1 \cdot 2^{2}$

Step 4

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

$- 1 \cdot 4$

Step 5
