(Answer аny fоur questiоns—eаch cоrrect аnswer is worth 3 points. You will earn 1 bonus point for each additional correct answer beyond the required four.) Consider the arguments below. If the argument is valid, identify its logical form. Otherwise, indicate whether the converse or inverse error is made. (1) is an irrational number. is greater than 8. Therefore, is an irrational number whose square is greater than 8. [a1] (2) If this graph can be colored with three colors, then it can be colored with four colors. The graph cannot be colored with four colors. Therefore, the graph cannot be colored with three colors. [a2] (3) If this graph can be colored with three colors, then it can be colored with four colors. The graph cannot be colored with three colors. Therefore, the graph cannot be colored with four colors. [a3] (4) The real number is greater than 4. Therefore, is greater than 4 or is not defined. [a4] (5) If the real number is greater than 2, then is positive. If is positive, then exists. Therefore, if is greater than 2, then exists. [a5] (6) is a rational number and is positive. Therefore, is a positive. [a6] (Hint: It is helpful to write each argument in a symbolic form.)
