Please explain these question to me ...
1)A system of m equations over F2 in n
unknowns has exactly 2n−m solutions.
• A. True
• B. False
answer: false
2)How many roots x [tex]\in[/tex] F2 does the polynomial
x2+x+1 have?
answer:0
3)Which of the following is a cube root of 8i? (Choose all correct answer)
A. sqrt(3)−i
B. −sqrt(3)−i
C. sqrt(3)+i
D. −2i
E. −sqrt(3)+i
answer: sqrt(3)+i( i think there is more?)
I have the answer, but I don't understand
also, those stuff is not in my textbook and the prof didn't give much example
... please help
