Answer: 6.302 ⋅ 10^7 kg

Step-by-step explanation:

Subtract the mass of freight train from the mass of the aircraft carrier:

(7.3 ⋅ 10^7) - (9.98 ⋅ 10^6)

Get both to have the same exponent (6) by moving the decimal on 73:

(73 ⋅ 10^6) - (9.98 ⋅ 10^6)

Subtract the leading numbers:

(73-9.98) ⋅ 10^6 = 63.02 ⋅ 10^6

Move the decimal back so the answer is in scientific notation:

6.302 ⋅ 10^7 kg
