Question
State whether the given pair of set is equal or equivalent.
P = {prime numbers which divide 70 exactly} and
Q = {prime numbers which divide 105 exactly}
Solution
P = {prime numbers which divide 70 exactly}
= {2, 5, 7}
and Q = {prime numbers which divide 105 exactly}
= {3, 5, 7}
These are equivalent sets as these have equal number of elements.
