When measurements are expressed to three significant figures, it means that only the first three digits that contribute to the precision of the number are considered. This includes all non-zero digits, any zeros between them, and trailing zeros if they are to the right of a decimal point. For example, the number 0.00456 would be expressed as 4.56 × 10^(-3) in three significant figures. This practice helps in maintaining clarity and consistency in data representation.
