Let Z be the set of all integers and `A={(a, b):a^2 + 3b^2 = 28, a, b in Z) B = {(a, b) : a > b, a, b in Z}`. Then, the number of elements in `AnnB` , is

Let Z denote the set of all integers and A = { (a,b) : a^2 +3b^2 = 28 ,a,b in Z } and B= {(a,b ):a gt b, in Z} . Then the number of elements in A nn B is

Let Z be the set of all integers and A={(a,b):a^(2)+3b^(2)=28 ,a,b in Z} and B ={(a,b):a gt b in Z ) then the number of elements is A cap B , is

Let Z be the set of all integers and A={(a,b):a^(2)+3b^(2)=28 ,a,b in Z} and B ={(a,b):a gt b in Z ) then the number of elements is A cap B , is

Let Z denote the set of all integers and A={(a,b):a^(2)+3b^(2)=28,a,binZ} and B={(a,b):agtb,a,binZ} . Then, the number of elements in AnnB is a)2 b)3 c)4 d)6

Let 1 denote the set of all integers and A={(a,b):a^(2)+b^(2)=28,a,b in I}B={(a,b):a>b,a,b in I} then no of elements in A nn B is

Let Z be the set of all integers and let a*b =a-b+ab . Then * is

Let Z be the set of all integers and A={(x,y);x^(4)-y^(4)=175,x,y in Z},B={(,),x>y,x,y in Z} Then,the number of elements in A nn B is

For set {(a, b) : 2a^(2)+3b^(2)= 35, a, b in Z} the number of its elements is………..
