9.8*10^9
Just count how many times you need to divide by 10 to shrink to a single digit number, then multiply by 10 to that power

In scientific notation, a number is written as a * 10^b, where b denotes the number of digits before the decimal point minus 1, and you get a by shifting the decimal point such that the number before the decimal point consists of only 1 digit.
E.g., 100 = 1 * 10^2, because 100 = 100.00, and you shift the decimal point to the left by 2 places, thus you get a=1, and the number consists of 3 digits before the decimal point, thus b = 3-1 = 2.
9,800,000,000 = 9,800,000,000.00 consists of 10 digits before the decimal point, so b = 10-1 = 9, and you shift the decimal point to the left such that a = 9.8 only has one digit before the decimal point.
Thus, 9,800,000,000 = 9.8 * 10 ^9.
