Răspuns :
6/(a+1)*(b+2)-echiunitara
6=(a+1)*(b+2)
(a+1)*(b+2)=6
1. a+1=1
a=0
b+2=6
b=4
2. a+1=2
a=1
b+2=3
b=1
3. a+1=3
a=2
b+2=2
b=0
(a,b)∈{(0,4);(1,1);(2,0)}
6=(a+1)*(b+2)
(a+1)*(b+2)=6
1. a+1=1
a=0
b+2=6
b=4
2. a+1=2
a=1
b+2=3
b=1
3. a+1=3
a=2
b+2=2
b=0
(a,b)∈{(0,4);(1,1);(2,0)}
daca e echiunitara , atunci :
( a+1) ( b+2) = 6
a = 0 b =4
a =1 b= 1
a = 2 b = 0
( a+1) ( b+2) = 6
a = 0 b =4
a =1 b= 1
a = 2 b = 0
