Answer 1

[AI-generated answer — Explain Bot]

To determine the number of significant figures in a number, you need to count all the digits from the first nonzero digit, starting from the left.

In the number 2.300 * 10^-4, there are four digits: 2, 3, 0, and another 0. However, the first two zeros after the decimal point are not considered significant because they only serve to locate the decimal point. Therefore, the number of significant figures in 2.300 * 10^-4 is 3.
