Determine whether these are valid arguments,
a) If x is a positive real number, then .x2 is a positive real number. Therefore, if a2 is positive, where a is a real number, then a is a positive real number.
b) If x2 ≠ 0, where x is a real number, then x ≠ 0. Let a be a real number with a2 ≠ 0; then a ≠ 0.
