This question concerns the field GF(256). The modulus is P(x)=x8+x4+x3+x+1. For computing inverses in this field, you should use the table in the textbook. Please answer the following questions about arithmetic in this field. a) If p(x)=x7+x6+x3+1, and q(x)=x5+x4, what is p(x)/q(x)? b) If p(x)=x7+x3+x2+x, and q(x)=1, what is p(x)/q(x)?
