Question

Salut,ma poti ajuta la o tema caci nu am inteles-o...​

Answer 1

Explicație pas cu pas:

a ∈ {0, 1, 2, 3, 4, 5, 6}

$\dfrac{0}{3} = 0 ; \dfrac{1}{3}; \dfrac{2}{3}; \dfrac{3}{3} = 1; \dfrac{4}{3}; \dfrac{5}{3}; \dfrac{6}{3} = 2$

$A = \Big\{0 ; \dfrac{1}{3}; \dfrac{2}{3}; 1; \dfrac{4}{3}; \dfrac{5}{3}; 2 \Big\}$

x ∈ {1, 2, 3, 4}

$B = \Big\{\dfrac{5}{1} ; \dfrac{5}{2}; \dfrac{5}{3}; \dfrac{5}{4} \Big\}$

a ∈ {1, 2}; b ∈ {1, 2, 3, 6}

$\dfrac{1}{1} = 1 ; \dfrac{2}{1} = 2; \dfrac{1}{2}; \dfrac{2}{2} = 1; \dfrac{1}{3}; \dfrac{2}{3}; \dfrac{1}{6}; \dfrac{2}{6} = \dfrac{1}{3}$

$C = \Big\{1; 2; \dfrac{1}{2}; \dfrac{1}{3}; \dfrac{2}{3}; \dfrac{1}{6} \Big\}$
