DAU COROANA SI FOLLOW SI RATING 5 STELE CN IMI FACE EX ASTA CORECT!!!!​

Answer 1

Răspuns:

Explicație pas cu pas:

a) fractie supraunitara

25 > x^2 + y^2

x = 0; y = 1 / x = 0; y = 2 / x = 0; y = 3 / x = 0; y = 4

x = 1; y = 0 / x = 1; y = 2 / x = 1; y = 3 / x = 1; y = 4

x = 2; y = 0 / x = 2; y = 1 / x = 2; y = 3 / x = 2; y = 4

x = 3; y = 0 / x = 3; y = 1 / x = 3; y = 2

x = 4; y = 0 / x = 4; y = 1 / x = 4; y = 2

b) numar natural

x^2 + y^2 sa fie divizor al lui 25

x^2 + y^2 = 1, 5, 25

x = 1; y  = 0 / x = 0; y = 1

x = 1; y = 2 / x = 2; y = 1

x = 3; y = 4 / x = 4; y = 3
