Answer 1

1.a)A

b)F

c)A

d)F

2.

27-2=25

(19+16)-25=35-225=10 elevi

3.

a)A={1,2,3,4,8} B={0,5,7,8,3}

b)A={1,2,4,9}|^|B={0,1,5,4,9}|^|C={0,1,4,9,10}={1,4,9}

4.E={a,c,b,d}F={a,c}

5.

a){2,5,6}

b){2,5}

c){1,2,3,4,5,6}

d){3}

e){1,2,3,5}

d){1,2,3,5,6}

6.

a) M3={0 1 3 6 9 12 15 18 21 24 27 30 33 36 39......}

M3 pari >3 dar <40 sunt:{6 12 18 24 30 36}

Atunci Multimea A={6 12 18 24 30 36}

b)B={3 27 243} (3^1 3^3 3^5)

c)x-3=8

2x+2=18

x+1< sau = 6

x-3=8

x=8+3=11

2x=18-2=16

x=16:2=8

x=(0 1 2 3 4 5)

C={0 1 2 3 4 5 8 11}
