WebThe ring Z [ i] is a subring of C and therefore it is a domain (like every subring of a field). If you want to see it with computations, suppose a + b i ≠ 0 and ( a + b i) ( x + y i) = 0. This is equivalent to. { a x − b y = 0 b x + a y = 0. The determinant of the matrix is. det [ a − b b a] = a 2 + b 2 ≠ 0. so the system has only the ... Web17.4.

WebTherefore the divisors of 18 are (2 0 · 3 0), (2 0 · 3 1), (2 0 · 3 2), (2 1 · 3 0), (2 1 · 3 1), (2 1 · 3 2) making a total of 6 divisors which is 3 * 2. Naive Approach In this approach we would iterate over all the numbers from 1 to the square root of n checking the divisibility of an element to n while keeping count of the number of ... Web4. Find a unit p(x) in Z 4[x] such that degp(x) >1. Solution 4. (2x 2+2x+1) = 4x4 +4x2 +1+8x3 +4x2 +4x= 1 mod 4, so (2x +2x+1) is a unit. In fact, (2xn+2xn 1 + +2x+1) is a unit for any positive integer n. Indeed, let p(x) = xn+xn 1 + + x, then (2xn+ 2xn 1 + + 2x+ 1)2 = (2p(x) + 1)2 = 4(p(x))2 + 4p(x) + 1 1 mod 4: Therefore, in Z 4[x] we have units of every degree. 5.
