Question

Find the union set of X = { x : n E N,x = 2n, n < 4} and Y = {x : x is an even number less than 10}

Answer 1

Answer:-

Hence {A∩B=B}

Step-by-step explanation:

The given sets are:

A={x:x∈N}={1,2,3,4.....}

B={x:x=2n,n∈N}={2,4,6,8,10....}

C={x:x=2n−1,n∈N}={1,3,5,7,9.......}

D={x:x is a prime number}={2,3,5,7,11,13....}

∴ A∩B={1,2,3,4....}∩{2,4,6,8....}

={2,4,6,8....}

=B

Hence {A∩B=B}
