Answer:
Rust is the term we use to describe red iron oxides produced when ferrous metals corrode. Rust is the common name for the chemicals that result when iron reacts with oxygen and water. “Rust” is poorly defined in chemistry, however—lots of chemicals can be formed when iron is left exposed.
Step-by-step explanation:
It is known that for any non-empty set A, A×A×A is defined as
A×A×A={(a,b,c):a,b,c∈A}
It is given that A={−1,1}
A×A×A={(−1,−1,−1),(−1,−1,1),(−1,1,−1),(−1,1,1),(1,−1,−1),(1,−1,1),
(1,1,−1),(1,1,1)}
