![\dfrac{4^8}{(4^2)^{-3}}\div 4^4=\dfrac{4^8}{4^{-6}\cdot4^4}=\dfrac{4^8}{4^{-2}}\\\\=4^8\cdot4^2=4^{10}](https://tex.z-dn.net/?f=%5Cdfrac%7B4%5E8%7D%7B%284%5E2%29%5E%7B-3%7D%7D%5Cdiv%204%5E4%3D%5Cdfrac%7B4%5E8%7D%7B4%5E%7B-6%7D%5Ccdot4%5E4%7D%3D%5Cdfrac%7B4%5E8%7D%7B4%5E%7B-2%7D%7D%5C%5C%5C%5C%3D4%5E8%5Ccdot4%5E2%3D4%5E%7B10%7D)
The value of n is 10.

3. Using the above rules of exponents, the expression simplifies to ...
6^(-n+n) = 6^0 = 1
The value is 1 for any n.
