Fie multimile M= {x E (apartine) IN* | x+1<6}, P={x E (apartine) IN* | 3 supra x E (apartine) IN}.

a) M=...
b)P=...
c) P\M=...

a. 
M. x∈ |N*, x+1 < 6 => x<5 => x∈{1,2,3,4} => M= {1,2,3,4}

b.
P. x∈ |N* , [tex] \frac{3}{x} [/tex]∈ |N =. x| (divida) 3 => x∈{1,3} => P={1,3}

c. 
P\M = {multimea vida}
