Question

Prove that any finite set of real numbers has a maximum

Answer 1

If a finite nonempty set of real numbers has a maximum then it has a minimum, prove. Boundary of a Lebesgue measurable set E with λ n ( E ) ≠ 0 has Lebesgue Measure zero? Given the set A = { ( x , y ) ∈ R 2 : 1 < x 2 y 3 < 2 } , is an open or closed set and is it also bounded or unbounded?
