Answer 1

Răspuns:

Uite rezolvarile dar nu am reusit ex5 b.

Explicație pas cu pas:

B-A=(0,1,9,16)

5) a. A=(0,1,2)

  B=(-4,-3,-2,-1,0,1,2)

A reunit cu B=(-4,-3,-2,-1,0,1,2)

A intersectat cu B=(0,1,2)

A-B= Multimea vida

B-A=(-4,-3,-2,-1)

b.  

6) a. A=(4,5,6)

     B=(-3,-2,-1,0,1,2)

A reunit cu B=(-3,-2,-1,0,1,2,3,4,5,6)

A intersectat cu B= Multimea vida

A-B=(4,5,6)

B-A=(-3,-2,-1,0,1,2)

   

   b. A=(0,1,2,3,4)

      B=(-3,-2,-1,0,1,2,3,4)

A reunit cu B=(-3,-2,-1,0,1,2,3,4)

A intersectat cu B=(0,1,2,3,4)

A-B= Multimea vida

B-A=(-3,-2,-1,)
