    A) 4
    B) 1-4 depending (The trouble with trailing zeros is that you never know whether they are significant or not without additional information.)
    C) 3

    One way to identify significant digits is to look at the number of digits you need to write when you express the identical number in scientific notation.
    A) 5.002*100
    B) 5*103, or 5.0*103, or 5.00*103, or 5.000*103
    C) 6.89*10-4

        1) its 3 because the zeros in between the digits are considered significant
        2) 4 because it is actually 5000.00 and the zeros after decimals are never considered significant while digits before decimal are significant
        3) 3 same reson zeros after the decimals are not considered significant
