Answer:
A. A = B
Step-by-step explanation:
Given
![A = 8!](https://tex.z-dn.net/?f=A%20%3D%208%21)
![B = ^8P_8](https://tex.z-dn.net/?f=B%20%3D%20%5E8P_8)
Required
Which of the options is true
We start by simplifying ![B = ^8P_8](https://tex.z-dn.net/?f=B%20%3D%20%5E8P_8)
Permutation is calculated as follows
![^nP_r = \frac{n!}{(n - r)!}](https://tex.z-dn.net/?f=%5EnP_r%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n%20-%20r%29%21%7D)
So.
![^8P_8 =\frac{8!}{(8 - 8)!}](https://tex.z-dn.net/?f=%5E8P_8%20%3D%5Cfrac%7B8%21%7D%7B%288%20-%208%29%21%7D)
![^8P_8 =\frac{8!}{0!}](https://tex.z-dn.net/?f=%5E8P_8%20%3D%5Cfrac%7B8%21%7D%7B0%21%7D)
0! = 1; So
![^8P_8 =\frac{8!}{1}](https://tex.z-dn.net/?f=%5E8P_8%20%3D%5Cfrac%7B8%21%7D%7B1%7D)
![^8P_8 =8!](https://tex.z-dn.net/?f=%5E8P_8%20%3D8%21)
Hence. B! = P!
<em>This implies that </em>
