Let A, B, and C be three collinear points s.t. A*B*C. Prove
each of the follow set equalities. I'm really having trouble
applying theorems like the ruler placement postulate or betweenness
theorem to help prove these.

5. Prove that the following languages are not regular: (a) L = {amb’ak: k sn +1}. (b) L = {a” b'ak : kun +1}. (c) L = {a"b'ak: n=1 or 1 # k}.
Prove that each of the following languages is not regular A) L= {a^n b^m c^k : k = 2n + 3m and n, m, k ≥ 0} B) L = {a^n : n is a power of 5}
EXERCISE 7 Let B = {a"b4" I n 20. Using the pumping lemma for regular languages, prove that B is not regu
5. Let A={a,b,c} and let K, L C A be languages described as follows: K = {a"y":n in e Zo} and L = {a?,62,c2-free words over A}. Thus L is the language of all words over A that have no consecutive letters that are the same. (a) Give a recursive description of K. (b) Construct a finite state automaton (FSA) that accepts L.
Prove that the following are not regular languages. Just B and F

Prove that the following are not regular languages. {0^n1^n | n Greaterthanorequalto 1}. This language, consisting of a string of 0's followed by an equal-length string of l's, is the language L_01 we considered informally at the beginning of the section. Here, you should apply the pumping lemma in the proof. The set of strings of balanced parentheses. These are the strings of characters "(" and ")"...
Let A, B, C be three collinear points and let D, E, F be the midpoints of segments AB, BC, and AC, respectively. Prove that the segments DE and BF have the same midpoint. Let d be a line and let A, B, C be three points not on d. Prove that if d does not separate points A and B and it does not separate points B and C, then it does not separate points A and C.
2·Let Ω be a sample space and P be a probability. Prove that there can't exist events E, F that satisfy
