Answer 1

Răspuns:

Explicație pas cu pas:

a) {1,5,6,7} n {0,1,2,3,4} = {0, 1, 2, 3, 4, 5, 6, 7}

c) {2,4,6,8,10,...,46} n {2,12,22,32, ...,92} = {2, 12, 22, 32, 42}

e) {1,5,6,7,8,9,10,11,12} n {0,1,2,3,4,10,11,13,15} = {1, 10, 11}

g) {1,5,6,7} - {0,1,2,3,4}  = {5. 6, 7}

i) {2,3,4,5,6} - {0,1,2,8,9,10}  = {3, 4, 5, 6}

b){2,3,4,5,6} n {0,1,2,8,9,10)  = {2}

d){1,2,3,4} {1,2,3,5,6)  - nu ai scris operatia intre multimi

1) (2,4,6,8,10) U {2,3,4,5,6}  = {2, 4, 6, 8, 10, 3, 5}

h) {1,2,3,4} - {1,2,3,5,6)​ = {4}
