A∩B={3,5,7,9}
1) In this question, we are going to find the set A intersection B, so let's pick the common numbers within the set A and B and write them as A∩B.
2) Note the following sets:
A={1,2,3,4,5,6,7,8,9,10}
B={3,5,7,9,11,13}
Let's bold the numbers that are simultaneously at A and B
A={1,2,3,4,5,6,7,8,9,10}
B={3,5,7,9,11,13}
3) Thus we can write A∩B as A∩B={3,5,7,9}
