#### Answer

$M \cap U = \left\{0, 2, 4, 6, 8\right\}$

#### Work Step by Step

The symbol $\cap$ represents intersection of sets.
The intersection of sets M and U is the set that contains all the common elements of M and U.
The elements that are common to M and U are 0, 2, 4, 6, and 8.
Thus, $M \cap U = \left\{0, 2, 4, 6, 8\right\}$.
