The goal of writing a number in scientific notation is to have a decimal number,with one digit to the left of the decimal point,followed by a x10 to some power.To format the number this way,divide the 349786.730496 by 10 5 times,making it 3.49786730.Each division by 10moves the decimal point to the right on digit,but in order to keep the same number, multiply 3.49786730 by 10^5,3.49786730 x 10^5.
