9. Let U = {a,b,c,d,e,f.g} be the universal set and A = {a, c, e) and B = {a,c,g) be subsets of U. Compute fans (e) where fx is the indicator of characteristic function of set X. Ans 10. Find the greatest common divisor and least common multiple of the numbers 12345 and 67890. If d is the greatest common divisor, finds and t such that d = sa + tb. 9.
