Answer: A.
Step-by-step explanation:
Answer:
b, since the others have the input and output on the wrong sides
The difference between the masses is
4.55·10¹³ kg -1.78·10¹² kg
= 4.55·10¹³ kg - 0.178·10¹³ kg
= (4.55 -0.178)·10¹³ kg
= 4.372·10¹³ kg
Rounded to the appropriate precision, the mass of the Antarctic iceberg exceeds that of the Rock of Gibraltar by ...
4.37·10¹³ kg
The 4^10 and 4^5 can be simplified. So the answer is:
10^4 x 4^5
