Question

set a is equals to flower bracket x x belongs n and X is a multiple of 4 less than 20 flower bracket ​

Answer 1

Answer:

A = {x:x is a natural number and multiple of 3} = {3,6,9…}

As, B = {x:x is a natural number less than 6} = {1,2,3,4,5,6}

A∪B = {1,2,4,5,3,6,9,12…}

∴, A∪B = {x:x=1,2,4,5 or a multiple of 3}

Answer 2

Given, A={x:xisamultipleof4}

={4,8,12,16,20,…}

and B={x:xisamultipleof6}

={6,12,18,24,…}

∴A∩B={12,24,…}

={x:xisamultipleof12
