Error made by the guide has to be explained using the concept of significant figures. Concept Introduction: Precision is a state which tells about the closeness of the result to each other in an experiment. During a measurement, significant figures are used to tell about the uncertainty present in it. There are six rules for determining the number of significant figures. They are given as follows. Nonzero digits and the zeros that are present between nonzero digits are significant. Zeros that are used merely to position the decimal are not significant. If zeros are present in the right end of the decimal point, then the zeros are significant. If zeros are present in the result are not in right of the decimal point, then the zeros may or may not be significant. If the zeros disappear when scientific notation is used means then those zeros are not significant. Exact numbers have no limit to their precision and they do not obey the rules given for significant figures.

Concept Introduction:

Precision is a state which tells about the closeness of the result to each other in an experiment. During a measurement, significant figures are used to tell about the uncertainty present in it.

There are six rules for determining the number of significant figures. They are given as follows.

Nonzero digits and the zeros that are present between nonzero digits are significant.

Zeros that are used merely to position the decimal are not significant.

If zeros are present in the right end of the decimal point, then the zeros are significant.

If zeros are present in the result are not in right of the decimal point, then the zeros may or may not be significant.

If the zeros disappear when scientific notation is used means then those zeros are not significant.

Exact numbers have no limit to their precision and they do not obey the rules given for significant figures.
