Answer:
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)
