The mass of a freight train is 9.98 • 10^6 kg the mass of an aircraft carrier is 7.3 •10^7 approximately how many more kilogram is the mass of an aircraft carrier than the mass freight train?

63'020'000 kg or 6.302 * 10^7

Step-by-step explanation:

Freight train = 9.98 • 10^6 = 9'980'000 kg

Aircraft carrier = 7.3 •10^7 = 73'000'000 kg

Thus 73000000 kg - 9'980'000 kg = 63'020'000 kilogram =

= 6.302 * 10^7

(scientific notation)

= 6.302e7

(scientific e notation)

= 63.02 * 106

(engineering notation)

(million; prefix mega - (M))

= 63020000

(real number)
