a) Simplify the following: the set from the photo b) Based on your “experimental” results from part a), make a general conjecture, in the form of an equation that you think will be true for all positive integers n, whose left-hand side for n = 1,2,3,4 gives you the four fractions listed in part a) (and whose right-hand side agrees with the results you found). Do not try to prove your conjecture at this stage. c) Assuming your conjecture from part b) is true, what expression do you get for 1+4+9+···+n^2 ? Again, don’t worry about proving this yet.
