12. A question about approximate number. There is an approximate number: "1.2 × 10 ∧ 4". Question: which digit is it accurate to? I think there are two kinds of answers: 1. If you only look at 1.2 (because you only look at 1.2 when you look at the significant number), then it is accurate to the tenth digit; 2. If you write this number as 12000, then it is accurate to the thousand digit; is the correct answer 1 or 2, or something else?
