P={2, 1,3, 9, 1/2}; Q = {1,21/2,3, 7} and R = {5, 4, 21/2}. Find P∪Q∪R
Question 1 Report
P={2, 1,3, 9, 1/2}; Q = {1,21/2,3, 7} and R = {5, 4, 21/2}. Find P∪Q∪R
Answer Details
To find P∪Q∪R, we need to combine all the elements in P, Q and R, without repeating any element. The elements in P are {2, 1, 3, 9, 1/2}. The elements in Q are {1, 2^(1/2), 3, 7}. The elements in R are {5, 4, 2^(1/2)}. So, P∪Q∪R = {1/2, 1, 2, 2^(1/2), 3, 4, 5, 7, 9}. Therefore, the correct answer is (1/2, 1, 2, 21/2, 3, 4, 5, 7, 9).
