The inverse proposition, no proposition and inverse no proposition that the square of any real number is nonnegative In this topic, "any" is a full quantifier. Can it become an existential quantifier when it is rewritten into the form of "if ~"? If it can be changed, how can it be changed
If x is any real number, then x & # 178; ≥ 0
So the inverse proposition is: if X & # 178; ≥ 0, then x is any real number. In other words, if the square of a number is non negative, then the number is any real number
In other words, there is a non real number such that its square is negative
The converse proposition is: if X & # 178; < 0, then x is not a real number. In other words, if the square of a number is negative, then the number is not a real number
