Expert Solution

Answer to Problem 1RE

Solution:

The answer is yes, AB.

Explanation of Solution

Given Information:

The given sets are A={ 1,2,5,7 }

and B={ x:xand is a positive integer,x8 }.

Explanation:

Let us convert the set B in another form.

B={ 1,2,3,4,5,6,7,8 }

We see that every element of A is an element of B.

So, { 1,2,5,7 }{ 1,2,3,4,5,6,7,8 }

Therefore, AB.
