If A xxB = {(a , x), (a , y), (b , x), (...

If `A xxB = {(a , x), (a , y), (b , x), (b , y)}`. Find A and B.

Text Solution

Verified by Experts

Given `A times B ={(a,x),(a,y),(b,x),(b,y)}`
A is a set of all first elements
`A={a,b}`(since first element contains only one element)
and B is a set of all second elements .
`B={x,y} ` (since second element contains only x and y
