(b) Each integer has the property that its square is less than or equal to its cube. i. Original statement: ii. Negation: iii. Which is true and why? (c) Every element in the set {0, 1,2} is greater than or equal to half of its square. i. Original statement: ii. Negation: iii. Which is true and why?

Create a truth table according to these specifications: There are 3 input bits, x2, x1, x0, and 2 output bits, s1, s0. The 2-bit output is the largest number of consecutive I's in the 3 input bits. (x2 is the most significant bit of the input, and s1 is the most significant bit of the output.) For example, input 000 gives output 00 (no 1’s), inputs 001 and 010 give output 01, input 011 gives output 10, etc. Show all 8 rows of the table clearly.
