Not sure how many significant figures are needed....
0.41
6 (the 6 is terminating)0.41
0.40

x
Your answer would turn out to be
D. 20+21i
I interpret the first number to be 89.24, so 84 and 24 hundredths.
The difference would be by how many numbers they differ, so we subtract the smaller from the bigger:
89.24-17=12.24
this would be their difference!
