Question

The square of an irrational number is irrational.
(a) Write the statement more formally, using quantification symbols (∀, ∃).
(b) Write an informal negation of the statement. Be sure to avoid negations that are ambiguous.
(c) Write a more formal negation of the statement, using quantification symbols (∀, ∃).
(d) Is the original statement true or false? If true, explain. If false, give a specific counterexample.
(e) Write an informal converse of the original statement.
(f) Write a more formal converse of the original statement, using quantification symbols (∀, ∃).
(g) Write an informal contrapositive of the converse of the original statement (i.e., a contrapositive of your statement in part (e)).
(h) Write a more formal contrapositive of the converse of the original statement, using quantification symbols (∀, ∃). (i) Is the converse of the original statement true or false? If true, explain. If false, give a specific counterexample.

The square of an irrational number is irrational.
(a) Write the statement more formally, using quantification symbols (V, 3).
