R is the set of positive even integers less than 201, and S is the set of the squares of the integers in R.   How many elements does the intersection of R and S contain?   R=2,4,6,8,10,12...   S=4,16,36,64...   Numbers: 4, 16, 36, 64, 100, 144, and 196 are even integers (less than 201) that are in both sets.   Solution: Seven   Answer: Seven
