The questions that follow are intended to provoke your thinking about some of the issues mentioned above. (a) Find three prominent open questions conjectures in mathematics, and record their precise state- ments on your paper (b) Let us accept CL as our working environment for this part of problem #3. Here, we will investigate some claims about the rationality irrationality of certain numbers. Recall that a real numberz is rutional if there exist integers m and n, with n 0...
