Work Step by Step

We start with the given expression: $5xy^0$ The zero as an exponent rule states that for every nonzero number $a$, $a^0=1$ We can use this rule to rewrite the expression as $5x\times1$ The identity property of multiplication states that the product of any real number and $1$ is the original number. Using this property, we figure out that the simplified version of the expression is $5x$.
