Answer:
Explanation:
What this proves is that teachers shouldn't assume that people can figure out how the calculator displays things. Time should be taken so you'd know the answer from class.
The two answers you want are the second one form the bottom and the third one from the top.
The third one from the top is 8*10^3
10^3 = 10 * 10 * 10 = 1000
8 * 10^3 = 8 * 10 * 10 * 10 = 8000
8000 is the answer written as a number.
All three are the same thing 8E3 means 8 * 10^3 = 8000
