Which of the following sets are rings with respect to the usual operations of addition and multiplication? If the set is a ring, is it also a field? can you explain in detail, I really do not understand how to prove.
-
Q(√2,√3)={a+b√2+c√3+d√6:a,b,c,d∈Q}
-
R={a+b3√3:a,b∈Q}
Solutions
Expert Solution
Since for (b) R={a+b3√3:a,b€Q } is not a ring so not field
For (a) Q(√2,√3) I have proved that it is field
Since their are various ways to proof it is field.
