Question

2. Find the intersection of each of the following pairs of sets. P = {x: nen, x = 3n n< 3}
Q = {x:XEN X < 7}​

Answer 1

Step-by-step explanation:

A = {x:x is a natural number and 1<x≤6} = {2,3,4,5,6}

B = {x:x is a natural number and 6<x<10} = {7,8,9}

A∪B = {2,3,4,5,6,7,8,9}

∴, A∪B = {x:x∈N and 1<x<10}.
