Answer 1

Answer:

hi

Step-by-step explanation:

a proof by contradiction of a conditional statement P→Q, we assume the negation of this statement or P∧⌝Q. So in a proof by contradiction of Theorem 3.20, we will assume that r is a real number, r2=2, and r is not irrational (that is, r is rational).
