Question

$\left[2\right]A=\{3k-1,kϵ\},B=\{2k-1,kϵ\}$, find $A\bigcap B$

Answer 1

$A=\{3k-1,k\}$ $\{Ink\ge 1\}$

$A=\left\{\right(2,1),(5,2),(8,3),.....(3k-1,k\left)\right\}$

$B=\{2k-1,k\}$

$B=\left\{\right(1,1),(3,2),(5,3),.....(2k-1,k\left)\right\}$

$\because$ no element of pair of element is

common in both the sets A and B,

$\therefore$ $A\cap B=\varphi$
