Given a = {1, 2, 3}, b = {2, 4, 6} and c = {1, 2, 3, 4, 5, 6}, then a ∩ (b ∩ c) = {} {2} {1, 2, 3, 4, 5, 6, 7, 8}

{2}

Explanation:

The symbol ∩ refers to intersection which means the common elements between two sets

We are given that:

A = {1, 2, 3}

B = {2 , 4, 6}

C = {1, 2, 3, 4, 5, 6}

Now, we are asked to get A ∩ (B∩C)

1- Let's start with what's in the brackets:

B∩C refers to the common elements between B and C

B∩C = {2, 4, 6} ∩ {1, 2, 3, 4, 5, 6} = {2, 4, 6}

2- Now. let's consider A ∩ (B∩C):

This means the common elements between set A and the set we got from part 1

A ∩ (B∩C) = {1, 2, 3} ∩ {2, 4, 6} = {2}

Hope this helps :)

answer: re

step-by-step explanation: idk buddy

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
