Question

M = ( x:x is a natural number and multiple of 3) N = ( x:x is a prime number less than 19 )find the union of this question

Answer 1

Set M = { x : x is a natural number and a multiple of 3 }

=> M = { 3, 6, 9, 12, 15, ... }

Set N = { x : x is a prime number less than 19 }

=> N = { 2, 3, 5, 7, 11, 13, 17 }

So M ∪ N will be = { 2, 3, 5, 6, 7, 9, 11, 12, 13, 15, 17, .... }

Hope it helped !

Answer 2

Answer:

M ∪ N will be = { 2, 3, 5, 6, 7, 9, 11, 12, 13, 15, 17, .... }

Step-by-step explanation:

Given two sets in set builder form

$\text{M = { x : x is a natural number and a multiple of 3 }}$

$\text{N = { x : x is a prime number less than 19 }}$

we have to find the union of these two sets.

$\text{M = { x : x is a natural number and a multiple of 3 }}$

$M=\{3, 6, 9, 12, 15, ... \}$

$\text{N = { x : x is a prime number less than 19 }}$

$N = \{ 2, 3, 5, 7, 11, 13, 17 \}$

M ∪ N={3, 6, 9, 12, 15, ...} ∪ { 2, 3, 5, 7, 11, 13, 17 }

M ∪ N={2, 3, 5, 7, 11, 13, 17, 3, 6, 9, 12, 15, ...}

so M ∪ N will be = { 2, 3, 5, 6, 7, 9, 11, 12, 13, 15, 17, .... }
