I'm not exactly sure why set U is included in this problem as it is irrelevant to the original question.

$$\text{A}=\{4,5,6,10\}\hspace{1mm}\text{and}\hspace{1mm}\text{B}=\{4,5,10\}$$

$$\text{A}\cap \text{B}=\hspace{1mm}?$$

$$\text{A}\cap \text{B}$$ is mathematical notation for the intersection of sets A and B. The intersection of two sets is a new set that contains all the elements from the individual sets. This means that all the numbers in set A and B will be smooshed into a new set.

$$\text{A}\cap \text{B}=\{4,5,6,10\}$$
