Homework Statement
Given two sets of Cartesian product
S=A1×A2...×An
P=(A1×A2...×An-1)×An
show that there exists bijection between the two sets.
Homework Equations
∀a1,a2:a1∈A1, a2∈A2: A1×A2=(a1,a2)
The Attempt at a Solution
let f be a function that maps
f: P → A1×A2...×An-1 where f((A1×A2...×An-1))∈A1×A2...×An-1 and f(An)∈Anis this correct?
