Question

Write in roster form:
{x:x=n³, n€W and n<6}​

Answer 1

It is clear that both sets A & B is a collection of only integers(z) such that range of ’n' is from -ve infinity to +ve infinity

A={-ve infinity,..,-12,-8,-4,0,4,8,12…,+ve infinity} (multiples of 4)

B={-ve infinity,..,-12,-9,-3,0,3,9,12…,+ve infinity} (multiples of 3)

Intersection is a operation used to collect similar elements in given sets.

So the starting elements are -12[ (3n=12,n=-4) & (4n=-12,n=-3) ] 0(when n=0),12[ (3n=12,n=4) & (4n=12,n=3) ] and so on.
