Web23 mrt. 2015 · To see if 4 n > n 3 for all n > 1, first establish bench marks. For n = 1, we see that 4 1 = 4 > 1 3 = 1 checks. For n = 2, we see that 4 2 = 16 > 2 3 = 8 checks. Now, assume that the inequality is true for some k > 2. Then, 4 k > k 3. Let's test to see if 4 k + 1 > ( k + 1) 3. 4 k + 1 = 4 ( 4 k) > 4 ( k 3) Now, compare 4 ( k 3) to ( k + 1) 3. Web10 apr. 2024 · Under GRH, the distribution of primes in a prescribed arithmetic progression for which g is primitive root modulo p is also studied in the literature (see, [ 8, 10, 12 ]). On the other hand, for a prime p, if an integer g generates a subgroup of index t in ( {\mathbb {Z}}/p {\mathbb {Z}})^ {*}, then we say that g is a t -near primitive root ... WebOriginal Statement: if n is a positive integer then n is even if and only if is 7n+4 is even. Contrapositive: If n is negative integer then n is odd if and only if 7n+4 is odd. Therefore by definition of odd: n = 2k+1 Substitute n: =7 (2k+1)+4 =14k+7+4 =14k+11 =2 (7k)+11 Therefore, n is odd and 7n+4 is odd.
