Work Step by Step

We start with the given expression: $x^0y^2$ We plug in the given values for $x$ and $y$: $2^0(-3)^2$ The zero as an exponent rule states that for every nonzero number $a$, $a^0=1$. We use this to simplify the exponents: $1\times9$ We apply the identity property of multiplication to simplify: $9$
