$2 x^{0} y^{- 2}$

Step 1

Anything raised to $0$ is $1$ .

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

Step 2

Multiply $2$ by $1$ .

$2 y^{- 2}$

Step 3

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$2 \frac{1}{y^{2}}$

Step 4

Combine $2$ and $\frac{1}{y^{2}}$ .

$\frac{2}{y^{2}}$
