Example 13 Identify the quantifiers and write the negation of the following statements (i) There exists a number which is equal to its square. (ii) For all even integers x, x² is also even. (iii) There exists a number which is a multiple of 6 and 9.
Use quantifiers to write the statement "Every natural number is odd or even." Then write its negation (again, using quantifiers).

. If the domain consists of all animals, express the following statements in terms of quantifiers and logical connectives, where B ( x ) = x is a bear, G ( x ) = x raids garbage cans, H ( x ) = x loves honey, and T ( x ) = lives in tents. A bear lives in a tent. Bears love honey. Only bears raid garbage cans. No bear lives in a tent. Some bears do not love honey.
Prove whether (¬p0g)0 (r O¬s) Op) and –ro-pare logically equivalent or not. To fill the blank spaces, consider the following table: V 1 2 4 5 7 8. 9. Consider the last 5 digits of your IDs. Assume that the last 5 digits of your ID are 12075. My id last 5 digit : 14271 Now, follow the chart and select your operators sequentially. For example, for having ID 12075 the operators will be: 1 =v 2 = - 0 =A 7=- 5 =0 So you have to prove whether (¬pvq)→(r A¬s) → t) and re-p are logically equivalent or not. If a student has ID with less than 5 digits then he will put 0 at the beginning to make it 5 digits.
Use universal instantiation or universal modus ponens to fill in a valid conclusion for the following argument. If a computer program is correct, then compilation of the program does not produce error messages. Compilation of this program produces error messages. O This computer program is not correct. O The error message is correct. O Compilation of this program does not produce error messages. O This computer program is correct. O The error message is not correct.
