Answer:
8.760 x 10^3
Step-by-step explanation:
There are 8760 hours in 1 year. So, you can convert this to scientific notation by moving the decimal from 8760 three times to the left: 8760. → 8.760 And since it was moved three times, put an exponent of 3 to the 10: 10^3 So, you get 8.760 x 10^3 hours in a year.
Hope this helps! :)
