This question concerns the field GF(256). The modulus is P(x) = x³ + x² + 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) = x² + x¹ + x² + x + 1, and g(x) = x² + x³ + x² + x³ + x² + x + 1, what is p(x)/q(x)? b) If p(x) = x² + x³ + x² + x + 1, and q(x) = x² + x4 + x² + 1, what is p(x)/q(x)?
