Answer:
Option (A)
Step-by-step explanation:
The given expression is,
![(5^{-2}\times 4^{-4})^{-2}](https://tex.z-dn.net/?f=%285%5E%7B-2%7D%5Ctimes%204%5E%7B-4%7D%29%5E%7B-2%7D)
Since
and ![\frac{1}{x^{-1}}=x](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%5E%7B-1%7D%7D%3Dx)
![5^{2}=\frac{1}{5^{-2}}](https://tex.z-dn.net/?f=5%5E%7B2%7D%3D%5Cfrac%7B1%7D%7B5%5E%7B-2%7D%7D)
![4^{2}=\frac{1}{4^{-2}}](https://tex.z-dn.net/?f=4%5E%7B2%7D%3D%5Cfrac%7B1%7D%7B4%5E%7B-2%7D%7D)
Therefore, ![(5^{-2}\times 4^{-4})^{-2}=\frac{1}{(5^{-2}\times 4^{-4})^{2}}](https://tex.z-dn.net/?f=%285%5E%7B-2%7D%5Ctimes%204%5E%7B-4%7D%29%5E%7B-2%7D%3D%5Cfrac%7B1%7D%7B%285%5E%7B-2%7D%5Ctimes%204%5E%7B-4%7D%29%5E%7B2%7D%7D)
![=\frac{1}{(5^{-2})^2\times (4^{-4})^2}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B%285%5E%7B-2%7D%29%5E2%5Ctimes%20%284%5E%7B-4%7D%29%5E2%7D)
![=\frac{1}{5^{-4}\times 4^{-8}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B5%5E%7B-4%7D%5Ctimes%204%5E%7B-8%7D%7D)
![=\frac{1}{5^{-4}}\times \frac{1}{4^{-8}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B5%5E%7B-4%7D%7D%5Ctimes%20%5Cfrac%7B1%7D%7B4%5E%7B-8%7D%7D)
