in the group R* find elements a and b such that |a|=inf, |b|=inf and |ab|=2

Expert Solution

The identity element in the group is .

Suppose and .

As there is no such that so we can conclude that . Also as there is no such that so we can conclude that

Now

Hence , but .

Suppose A and B are subsets of R, and deﬁne: d(A,B) = inf{|a−b| : a ∈ A,b ∈ B}. (a) Show that if A∩B 6= ∅, then d(A,B) = 0. (b) If A is compact, B is closed, and A∩B = ∅, show d(A,B) > 0. (c) Find 2 closed, disjoint subsets of R (say A and B) with d(A,B) = 0

Elements Beryllium,Magnesium,Calcium, and Strontium are elements in group 2. These elements are relatively reactive-they will react with oxygen,acid and bases. Consequently they are found as minerals and are combined with other elements. What is mineral? These minerals have monetary value to a variety of global industries. Where in the world would you mostly likely find minerals (or pure forms)of each of these elements in groud 2,periods 2-5?
