Final answer:
The logical expression ¬∃x (¬Ix ∧ Mx) translates to 'There is no number that is not irrational and also a number,' implying that all numbers are either rational or not a number.
Step-by-step explanation:
The given expression ¬∃x (¬Ix ∧ Mx) is a formal logical statement that can be translated into a natural language sentence. The symbols used here are from the domain of propositional logic or predicate logic. The symbol ¬ stands for 'not,' ∃ for 'there exists,' ∧ for 'and,' I could represent an attribute 'is irrational,' M could represent 'is a number,' and x is a variable that can refer to any object.
To turn this logical proposition into a natural-sounding sentence, we need to interpret the logical connectors and quantify properly. The sentence would read something like this: 'There does not exist an x such that x is not irrational and x is a number.' This can be simplified to a more natural expression: 'There is no number that is not irrational and also a number', meaning all numbers are either rational or not a number at all.
