Answer
$A\cap U = \{1, 3, 5, 7\}$
Work Step by Step
Represented using the roster method, the four sets are:
$U = \{0, 1, 2, 3, 4, 5, 6, 7, 8\}$
$A = \{1, 3, 5, 7\}$
$B = \{0, 2, 4, 6, 8\}$
$C = \{2, 3, 4, 5\}$
The intersection of A and U is the set that contains all elements of A that are also elements of U.
$A\cap U = \{1, 3, 5, 7\}$
