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 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 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 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

Let Z be the set of all integers and let R be a relation on Z defined by a Rb implies a ge b . then R is

Let Z be the set of integers. If A = {x in Z : 2^((x + 2)(x^(2) - 5x + 6)} = 1 and B = {x in Z : -3 lt 2x - 1 lt 9} , then the number of subsets of the set A xx B is
