anonymous · Answer

n=0 right?  so its 81? or is it 0?

anonymous · Answer

Yeah. Plug in 0 for n.

The answer is 324 but I don't understand how they got it.  Its roots and radicals.

anonymous · Answer

Do they provide an explanation?

anonymous · Answer

it doesnt seem to make sense there

anonymous · Answer

No there is a radical sign in front of the n +81

anonymous · Answer

$$36\sqrt{n+81}$$ ? is that it?

anonymous · Answer

Oh ok. That makes sense.
$$C = 36\sqrt{n + 81}$$$$C = 36\sqrt{0 + 81}$$$$C = 36\sqrt{81}$$$$C = 36(9)$$$$C = 324$$
