Question
A number r ∈ R is called algebraic provided for some n ∈ N there exists numbers a0, a1, … , an ∈ Z such that r satisfies
p( r ) = 0
where p ( x ) = a0 + a1x + a2x2 + ⋯ + anxn.
A number r ∈ R is called transcendental provided it is NOT algebraic
prove the set of ALL algebraic numbers is countable and the set of ALL transcendental numbers is uncountable.
