Extend the automorphism ở: E→ E. We will show o has order 4: (e) Show (0²) = (-1+ √2)² 0². Thus, 7(0) = (-1+√2)0. Withou

Extend the automorphism ở: E→ E. We will show o has order 4: (e) Show (0²) = (-1+ √2)² 0². Thus, 7(0) = (-1+√2)0. Without loss of generality, let 7(0) = (-1+ √2) 0. (f) Show ²(0) = -0. (g) Verify (0)=-(-1+√2)0.
