8543241657891) Count the digits from right to left until you get to the next-to-last digit, 5. 8 54324165789 There are eleven digits, from the 9 to the 5. Write 10^112) Place a decimal point between the 8 and 5: 8.543241657893) Multiply by 10^11: 8.54324165789 x 10^11 854324165789 is 8.54324165789 x 10^11 in scientific notation.Notes: The intent of scientific notation is to reduce the visual complexity of large or small numbers. It is easier to compare numbers such as: 854324165789 and 5593039948389Quick, which one is larger?Finding the answer requires a little effort.But if they are both in scientific notation:8.54324165789 x 10^11, and5.593039948389 x 10^12We can quickly tell that the second is larger. We could also express the second value as 55.93039948389 x 10^11, so that they are directly comparable [both are now x 10^11].If these were measurements, the convention is to use "significant figures," (sig figs) which means to report only those numbers for which the measurement is accurate. Is the measuring device accurate to the precision suggested by these numbers? Often, numbers such as these are truncated to the sig figs of the measurement. If a car odometer were used for these values, it is likely only calibrated to the nearest foot or meter. In that case, these numbers would only be significant to perhaps 2 decimal points, and would be rewritten as: 8.54 x 10^11, and 5.59 x 10^12
