Answer:
3
Step-by-step explanation:
For f(x) = x^3 -2x^2 -7x +5 and x=1/(2-√3), we have ...
f(x) = ((x -2)x -7)x +5
and ...
x = 1/(2-√3) = (2+√3)/(2^2 -3) = 2+√3
Then ...
f(2+√3) = ((2 +√3 -2)(2 +√3) -7)(2 +√3) +5
= (3+2√3 -7)(2+√3) +5
= 2(√3 -2)(√3 +2) +5 = 2(3 -4) +5 = -2 +5
f(1/(2 -√3)) = 3
_____
If you really mean x = (1/2) -√3, then f(x) = (42√3 -3)/8.

Answer:
![64c^{6}](https://tex.z-dn.net/?f=64c%5E%7B6%7D)
Step-by-step explanation:
We know that ![(a*b)^{m}=a^{m} *b^{m}](https://tex.z-dn.net/?f=%28a%2Ab%29%5E%7Bm%7D%3Da%5E%7Bm%7D%20%2Ab%5E%7Bm%7D)
Given ![(4c^{2})^{3}](https://tex.z-dn.net/?f=%284c%5E%7B2%7D%29%5E%7B3%7D)
Here a=4 and b=![c^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D)
Using the above property we get
= ![4^{3}*(c^{2})^{3}](https://tex.z-dn.net/?f=4%5E%7B3%7D%2A%28c%5E%7B2%7D%29%5E%7B3%7D)
We know that ![(a^{m})^{n}=a^{mn}](https://tex.z-dn.net/?f=%28a%5E%7Bm%7D%29%5E%7Bn%7D%3Da%5E%7Bmn%7D)
using the above property we get
=
=![64c^{6}](https://tex.z-dn.net/?f=64c%5E%7B6%7D)
