In each case below, apply the extended Euclidean algorithm to a, b € Z. Determine d = gcd(a, b), and find integers x, y = Z satisfying the Bézout identity: ax + by d Finally, determine whether or not b is a unit in Z/aZ. If it is a unit, provide its multiplicative inverse by using the Bézout identity. (a) a = 27, b = 8 (b) a = 34, b = 10 (c) a = = 102, b = 33
