In F17, 2 is a primitive 8th root of unity. Evaluate f(x) = 7x3+8x2+3x+5 at the eight powers of 2 in F17. Verify that the method requires at most 16 multiplications in F17.
You can can more clearly see the theorem on page 376-378 and the problem is on page 382 #6:
The Attempt at a Solution
I was able to find that the d=3, but am unclear on how I evaluate f(x) based of Theorem 3.
