However, these two results are of great importance and credit should go to Legendre for his work on them, although he was not the first to state the law of quadratic reciprocity since it occurs in Euler 's work of 1751 and also of 1783 (see ).
Kuid nende kahe tulemused on väga oluline ja krediidi peaks minema Legendre tema töö neile, kuigi ta ei olnud esimene riigi õiguse ruutkeskmised vastastikkuse kuna see toimub Euler 's tööle 1751 ja ka 1783 (vt ).
