G={x|x nr natural,44<x<45}​

Answer 1

Răspuns:

Explicație pas cu pas:

B={x|x este nr natural,2<x<10}

B = {3, 4, 5, 6, 7, 8, 9}

C={x|x nr natural,1<x<6}

C = {2, 3, 4, 5}

D={x|x nr natural nenul,x<2020}

D = {1, 2, 3, 4, ...., 2019}

E={x|x nr natural par,x<33}

E = {0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32}

F={x|x nr natural,203<x<204}

F = ∅

G={x|x nr natural,44<x<45}​

G = ∅

Answer 2

Bună!

B={x|x∈N, 2<x<10} ↔ B={3, 4, 5, 6, 7, 8, 9}

C={x|x∈N, 1<x<6} ↔ C={2, 3, 4, 5}

D={x|x∈N*, x<2020} ↔ D={1, 2, 3, 4, ..., 2019}

E={x|x∈N, x este par, x<33} ↔ E={0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32}

F={x|x∈N, 203<x<204} ↔ F=∅

G={x|x∈N, 44<x<45} ↔ G=∅
