It is irrational because it does not repeat a pattern nor does it stop.
        
             
        
        
        
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
hope this helps
