Question

let a= {x:x € z } ; b= { x:x is a multiple of 3,x €z find aintersection b

Answer 1

here...
A={...,-3,-2,-1,0,1,2,3,....}

And B={...-9,-6,-3,0,3,6,9,...}

And here B is clearly a subset of A.

And so A intersection B is B itself. [As A would be the universal set in this case. and B being a Subset of A]

Hope it Helps...
