Given:

U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.

Let

A = {x|x is a multiple of 2}

B = {x|x is a multiple of 5}

We will find A ∩ B

So, first, we will find the sets A and B:

[tex]\begin{gathered} A=\mleft\lbrace2,4,6,8,10\mright\rbrace \\ B=\mleft\lbrace5,10\mright\rbrace \end{gathered}[/tex]

A ∩ B will be the numbers that are in both A and B

So, the answer will be:

[tex]A\cap B=\mleft\lbrace10\mright\rbrace[/tex]
