Answer:
3+b
Step-by-step explanation:
So, you have 3 shelves and there is b books on each.
3+b
There is a set of rules to solve i to the power.
First off, you need to know this:
![{i}^{1} = i \\ i^{2} = - 1 \\ {i}^{3} = - i \\ {i}^{4} = 1](https://tex.z-dn.net/?f=%7Bi%7D%5E%7B1%7D%20%3D%20i%20%5C%5C%20i%5E%7B2%7D%20%3D%20-%201%20%5C%5C%20%7Bi%7D%5E%7B3%7D%20%3D%20-%20i%20%5C%5C%20%7Bi%7D%5E%7B4%7D%20%3D%201)
After the power of 4, it just starts to loop from 1. Knowing this, we can say the following:
![i ^{4k} = 1 \\ {i}^{4k + 1} = i \\ {i}^{4k + 2} = - 1 \\ {i}^{4k + 3} = - i](https://tex.z-dn.net/?f=i%20%5E%7B4k%7D%20%3D%201%20%5C%5C%20%7Bi%7D%5E%7B4k%20%2B%201%7D%20%3D%20i%20%5C%5C%20%7Bi%7D%5E%7B4k%20%2B%202%7D%20%3D%20-%201%20%5C%5C%20%7Bi%7D%5E%7B4k%20%2B%203%7D%20%3D%20-%20i)
Applying this, all we need to do is divide the power by 4 and determine the remainder.
![i ^{401} = \\ 401 \times 4 = 100 \: (1 \: left) \\ i^{401} = i^{4 \times 100 + 1} \\ k = 100 \\ {i}^{401} = i^{4 \times 100 + 1} = {i}^{4k + 1} = i](https://tex.z-dn.net/?f=i%20%5E%7B401%7D%20%3D%20%5C%5C%20401%20%5Ctimes%204%20%3D%20100%20%5C%3A%20%281%20%5C%3A%20left%29%20%5C%5C%20i%5E%7B401%7D%20%3D%20i%5E%7B4%20%5Ctimes%20100%20%2B%201%7D%20%5C%5C%20k%20%3D%20100%20%5C%5C%20%7Bi%7D%5E%7B401%7D%20%3D%20i%5E%7B4%20%5Ctimes%20100%20%2B%201%7D%20%3D%20%7Bi%7D%5E%7B4k%20%2B%201%7D%20%3D%20i)
So the answer is:
I'm not to sure is I'm right but I think the answer is A <span>No, it is not. The statement is not precise. A ray or a point could be part of a line. Hope this helps</span>
