How do you write a number in scientific and decimal notation?
A number written in normalized scientific notation has the format a x 10^b (where “a” is any real number greater than 1 but less than 10, the “x” is a multiplication sign, and the exponent “b” is an integer). Decimal notation is a number expressed in the customary base-10 format, using a decimal point to separate the whole and fractional parts of the number. Examples of numbers in decimal notation format converted to scientific notation: 5072.13 (decimal) <-------> 5.07213 x 10^3 (scientific) (notice that the decimal was moved three places to the left when converting from decimal notation to scientific notation, so the exponent is “3” in the scientific format). 0.000176 <----------> 1.76 x 10^-4 (the decimal was moved 4 places to the right, so the exponent is -4). 17.0001 <--------------> 1.70001 x 10^1 1,721,002,013 <--------------> 1.721002013 x 10^9 0.9997 <-------------> 9.997 x 10^-1 To convert from scientific notation back to decimal notation, just move the decimal the number of
