A is incorrect because the plants must die before piling up
B is incorrect because the plants must die and accumulate before compressing
C is incorrect because plants must die before being buried.
- i =

- Product rule of radicals: √ab = √a x √b
Firstly, factor out i: 
Next, apply the product rule of radicals here as such:

<u>Your answer is 5i√2, or the second option.</u>
5 37/100
5 is the whole part and you have 37 hundredths
I think your answer is 1,800
The sum of these numbers is 1771, so if you round up or down, whichever is closest, then you would get a total of 1,800.
I hope this helps!
