Suppose F = [√2] and K = [√3]. For contradiction, suppose that φ : F → K is a field isomorphism.
Then there ∃(a + b√2) ∈ [√2] s.t. φ(a + b√2) = √3. But we know that φ must map to . It follows then
that φ(a + b√2)2 = φ((a + b√2))2 = φ(a2 + 2ab√2 + b2 ) = √3 2 = 3. Then since φ is a homomorphism
and a, b ∈ , we have a 2 + 2ab√2 + b2 = 3. But then we must have that 2ab√2 = 0 ⇒ 2ab = 0 ⇒ a = 0 ∨
b = 0. If b = 0, then a 2 = 3 ⇒ a = √3 which is a contradiction. But b
