Question
1. Check whether the following set F forms a ?eld with respect togiven operations.
(a) F = {a + b2 R : a, b Q} considered asa a subset of R with respect to the usual operations of
addition and multiplication.
(b) F = {a + bi C : a, b, c Q} considered as a asubset of C with respect to the usual operations of
addition and multiplication.
(c) F = {a + b2 + c3 R : a, b, c Q} considered as a a subset of R with respect to the usualoperations
of addition and multiplication.
PLEASE PROVIDE PROOF. This was the hardest part forme. I can show isolated examples of instances that conform to afield but cannot prove it generally. If you are very good in thisarea, I have a few more questions that are similar including partsd. e. and f. of this same problem. I will post the question underthe same nickname. I WILL RATE LIFESAVER.
Thanks in advance, I hope someone can helpme.
