Write the negation of of the following statement: “For every pair of real numbers x and y if x < y, then there exists a rational number q such that x < q < y.”
For each one, state whether the statement is TRUE, FALSE. Then, state the negation:1.∃a(ais a prime number)2.∀a(ais a power of 2)3.∃a∃b(a+b <0)
In the domain of all real numbers, consider the predicate: P(x): √ x 2 = x a) Translate from symbols to English: (∀x)P(x) b) Provide a counter example to the above statement. c) Translate the negation ¬(∀x)P(x) to English.
Let P(a, b) and Q(a, b) be the open sentences defined by P(a, b) : a = b andQ(a, b) : a^2 − b^2 = 0, respectively, where the variables a and b can take any value in Z. Determine the truth value of the open sentence Q(a, b) ⇒ P(a, b) for each (a, b) ∈ {(2, −2),(5, 7),(3, 3)}. Explain your answers. (Z is the set of intergers)
