The rule about uncertain digits is that there can be one and only one estimated or uncertain digit in a measurement. 23.5 Three significant digits as all are non-zero numbers (see rule #1 above). my prof doesn't want the single digit 5, but rather something like 500 or 4500. a rectangle is 24.3 m long and 2.3 m wide. The two zeros between 7 and 8 are significant because they are between non-zero numbers (see rule #2 above). Round off each of the following numbers to two significant digits, and express the result in standard scientific notation. A person has a mass of 63.4 kg. If they put a decimal here then the zero would be the last significant figure. For example, the number 5.033 x 10 is equivalent to 5.033E23 (or 5.033e23).
