Question

How many significant digits are in the number:

730

BlackTom AI · Accepted Answer

To determine the number of significant digits in 730, we need to apply the standard rules for significant figures.
First, note that the value is written as 730 without a decimal point. In such cases, trailing zeros at the end of the number are not considered significant unless a decimal point is explicitly shown or there is some notation indicating significance (e.g., a bar over a zero, scientific notation, or a decimal point).
Option considerations:
- If you assume standard convention for 730 with no decimal point, the digits '7' and '3' are significant, while the trailing zero is not. This yields 2 significant figures.
- If the number were written as 730. (with a decimal point), or in scientific notation as 7.30 × 10^2, the trailing zero would be considered significant, giving 3 significant figures. Such notations convey extra precision that 730 without a decimal point does not.
- If further notation were provided (such as a line over the zero or explicit notation of significance), that could alter the count, but with the given plain integer 730, the conventional interpretation is 2 significant figures.
In summary, under the common convention for integers lacking a decimal point, 730 contains two significant digits: the 7 and the 3, while the trailing 0 is not considered significant unless additional notation indicates otherwise.
