Question

Quizplus · Accepted Answer

The significant digits in a number are the digits that carry meaning in terms of precision or accuracy. Zeros before non-zero digits are not significant. Zeros between non-zero digits are significant. Zeros at the end of a number (to the right of a non-zero digit) may or may not be significant depending on how the number is written. In the given number, 0.02560, there are four digits that are non-zero (2, 5, 6, and 0). Zeros before the 2 are not significant. Zeros between 2, 5, and 6 are significant. Zeros after the 0 may or may not be significant depending on how the number is written. However, since it is given that the number is written as 0.02560, we can assume that the zeros at the end are significant. Therefore, there are a total of four significant digits in the number 0.02560.
