Question

Let A={x/xЄN,x≤4},B={y/yЄN,y<3} .Find AxB and BxA​ I need immediate answers

Answer 1

Answer

AxB = {(a,x}, {b,x}, {c,x}, {a,y}, {b,y}, {c,y}} BxA = {{x,a}, {y,a}, {x, b}, {y, b}, {x, c}, {y, c} } AxA = {{a,a}, {a,b}, {a,c}, {b,a}, {b,b}, {b,c},

{c,a}, {c,b}, {c,c}}

BxB = {{x, xx, y}, {y, x}, {y, y}
