100 points if you show how you got the answer! the mass of a freight train is 9.98 ⋅ 10^6 kilograms. the mass of an aircraft carrier is 7.3 ⋅ 10^7 kilograms. approximately how many more kilograms is the mass of an aircraft carrier than the mass of a freight train? show your work and write your answer in scientific notation.

First, simplify each one.

9.98 x 10^6 = 9980000

7.3 x 10^7 = 73000000

Next, subtract the freight from the aircraft

73000000 - 9980000 = 63020000

Round the decimal point to the first significant digit, and place the amount of place values the decimal point moved to the left as a power sign, over 10.

63020000 = 6.302 x 10^7

6.302 x 10^7 is your answer
