To’g’ri javoblar * bilan belgilangan
1. Agar A={a/a+2n,n∈N va B={b/b/2n-1,n∈N to’plamlar berilgan bo’lsa, A∪V ni toping:
*A∪V=N
A∪V=Q
A∪V=R

2. Agar A={a/4≤a≤14, a∈N} va B={b/10<b<19, b∈N} to’plamlar berilgan bo’lsa, A∩B ni toping:
*A∩B={x/11≤x≤14,x∈N}
A∩B={x/4<x<19, x∈N}
A∩B={x/10<x<19, x∈N}
A∩B={x/11≤x≤19, x∈N}
