Answer
$(Q\cap M) \cup R = \left\{0, 2, 4\right\}$
Work Step by Step
RECALL:
(1) The symbol $\cup$ represents union of sets which lists down in a set the combined elements of the given sets.
(2) The symbol $\cap$ represents intersection of sets which lists down in a set the elements common to the given sets.
Use (2) to obtain:
$Q \cap M = \left\{0, 2, 4, 6, 8\right\}=M$
Use (1) above to obtain:
$(Q\cap M) \cup R
\\= \left\{0, 2, 4, 6, 8\right\} \cap \left\{0, 1, 2, 3, 4\right\}
\\ = \left\{0, 2, 4\right\}$
