Explanation:

The “significant figures” denotes the “number of important single digits” which is included from 0 to 9 in the “expression coefficient” in “scientific notation”. The “number” of “significant figures” in an expression shows the confidence or accuracy of a quantity.

· Any zeros between two significant numbers are significant.
