For the given isomorphic mapping of a subfield of E, give all extensions of the mapping to

Question:

For the given isomorphic mapping of a subfield of E, give all extensions of the mapping to an isomorphic mapping of E onto a subfield of Q̅. Describe the extensions by giving values on the generating set {√2, √3, -√5} for E over Q.
