Question

How are significant zeros identified

Answer 1

[AI-generated answer — Bot GPT 3.5]

Significant zeros in a number are identified based on their position in relation to the decimal point.

1. Leading zeros are not considered significant. For example, in the number 0.0034, the zeros before the 3 are not significant.

2. Zeros between non-zero digits are considered significant. For example, in the number 405, all three zeros are significant.

3. Trailing zeros in a decimal number are considered significant. For example, in the number 8.700, all three zeros are significant.

4. Trailing zeros in a whole number without a decimal point may or may not be significant. For example, in the number 5400, the two zeros could be significant or not, depending on the context in which the number is used.

In scientific notation, all zeros between the significant digits are considered significant. For example, in the number 6.02 x 10^23, both zeros are significant.
