In scientific notation, we want to have only one non-zero digit to the left of the decimal point. To achieve this, we move the decimal point 10 places to the left so that we have 4.8 as our new number. Then we multiply by 10 raised to the number of places we moved the decimal point, which is 10 (because we moved it 10 places to the left). This gives us 4.8 x 10^10, which is choice C.
