S 01. Let a be an element such that a? E Q, but a € Q. (1) Show that Q(a, V2) = Q(a + V2). (ii) Show that Q (21/3,i) = Q(B), where ß = 24/3 i and i? = -1. = (iii) How many elements are there in the basis of Q(B) over Q? Write down the basis. (iv) Draw a lattice diagram for the fields Q. Q(a), ((v2), 2(a + v2), Q(K), Q(a,b), and Q(a,b,v2).
