2015年9月10日 · I have to compute the Legendre symbol $(\frac{5}{p})$. If $p=2$, it is immediate to see that we have $5 \equiv 1 (\mod{2})$. let $p$ an odd prime. By quadratic reciprocity we …

2022年7月18日 · The probability of rolling an odd number is \(\dfrac{1}{2}\). P(roll a number less than five) The event roll a number less than five is F = {1, 2, 3, 4}. P(roll a number less than …

2018年1月12日 · Consider all the possible outcomes of rolling a die: we can get either #1,2,3,4,5,# or #6#. Of these, #1,3,# and #5# are odd. #3# of the #6# total outcomes are odd. …

1） p是5的倍数，p为奇数，所以p只要个位是5就可以满足条件。 那么p除以5余数为零，选A。 2） p+1是5的倍数，p+1的个位是0或5，则p的个位是9或4，因为p是奇数，所以p的个位是9， …

2009年12月9日 · The Legendre symbol (5/p) =1 means that 5 is a quadratic residue mod p. The number 4^2 = 16 = 5 (11) shows that 5 is a quadratic residue mod 11, however 11 = 1(5), not -1.

A six sided die has the values {1,2,3,4,5,6} on the faces. Of that list, {1,3,5,6} are either odd or greater than 5. We have 4 values we want (1,3,5,6) out of 6 total (1,2,3,4,5,6)

2019年3月9日 · The five triangles are numbered from 1 to 5. The spinner is spun until it lands on one of the five edges of the pentagon. What is the probability that the number it lands on is …

Que sont les objectifs de développement durable (ODD) ? Et pourquoi sont-ils importants ? Le Programme de développement durable à l'horizon 2030 constitue un modèle commun de paix …

2015年5月7日 · It is not by quadratic reciprocity that we find that $(p/5)=1$ when $p$ is congruent to $1$ or $4$ modulo $5$, it is by direct easy calculation. Reciprocity is used in the assertion …

2018年11月29日 · To check if $5$ is a quadratic residue $(\mod p)$ I write the equivalent Legendre symbol with the condition: $(5/p) = 1$ So I have for quadratic reciprocity $(5/p) = …
