Final answer:
The property illustrated by the statement 19×17=17×19 is the Commutative Property of Multiplication, which states the order of multiplication doesn't affect the product.
Step-by-step explanation:
The property used in the given statement, 19×17=17×19, is the Commutative Property of Multiplication. This property states that the order in which two numbers are multiplied does not change the product. In other words, a × b = b × a.
For example, in this case, whether we multiply 19 by 17 or 17 by 19, the product (or the final result) remains the same i.e., 323. Hence, this principle verifies the statement: 19×17=17×19.
