Since we have the symbol â‹‚, we are looking for the intersection of the given sets.
B&={2,4,6,8,10}
C&={3,5,7,8}
An intersection of two sets is the set that contains elements that are common in both sets. An element is in the intersection of B and C if it belongs to B and C at the same time.
B&={2,4,6, 8,10}
C&={3,5,7, 8}
B â‹‚ C &={ 8}
