Question

ajutor va rog!! va rog​

Answer 1

Explicație pas cu pas:

$(\overline {1x};\overline {3y}) = 1 \ , \ x \neq y$

se caută perechile prime între ele

pentru x = 0:

(10;31) = (2×5;31) = 1

(10;32) = (2×5;2⁵) = 2

(10;33) = (2×5;3×11) = 1

(10;34) = (2×5;2×17) = 2

(10;35) = (2×5;5×7) = 5

(10;36) = (2×5;2²×3²) = 2

(10;37) = (2×5;37) = 1

(10;38) = (2×5;2×19) = 2

(10;39) = (2×5;3×13) = 1

pentru x = 1:

...

$\dfrac{\overline {1x}}{\overline {3y}} \in \Big\{\dfrac{10}{31}; \dfrac{10}{33}; \dfrac{10}{37}; \dfrac{10}{39}; \dfrac{11}{30}; \dfrac{11}{32}; \dfrac{11}{34}; \dfrac{11}{35}; \dfrac{11}{36}; \\ \dfrac{11}{37}; \dfrac{11}{38}; \dfrac{11}{39}; \dfrac{12}{31}; \dfrac{12}{35}; \dfrac{12}{37}; \dfrac{13}{30}; \dfrac{13}{31}; \dfrac{13}{32}; \dfrac{13}{34}; \\ \dfrac{13}{35}; \dfrac{13}{36}; \dfrac{13}{37}; \dfrac{13}{38}; \dfrac{14}{31}; \dfrac{14}{33}; \dfrac{14}{37}; \dfrac{14}{39}; \dfrac{15}{31}; \dfrac{15}{32}; \\ \dfrac{15}{34}; \dfrac{15}{37}; \dfrac{15}{38}; \dfrac{16}{31}; \dfrac{16}{33}; \dfrac{16}{35}; \dfrac{16}{37}; \dfrac{16}{39}; \dfrac{17}{30}; \dfrac{17}{31}; \\ \dfrac{17}{32}; \dfrac{17}{33}; \dfrac{17}{35}; \dfrac{17}{36}; \dfrac{17}{38}; \dfrac{17}{39}; \dfrac{18}{31}; \dfrac{18}{33}; \dfrac{18}{35}; \dfrac{18}{37}; \\ \dfrac{18}{39}; \dfrac{19}{30}; \dfrac{19}{31}; \dfrac{19}{32}; \dfrac{19}{33}; \dfrac{19}{34}; \dfrac{19}{35}; \dfrac{19}{36}; \dfrac{19}{37}\Big\}$
