#### Answer

$Q \cap R' = \left\{6, 8, 10, 12\right\}$

#### Work Step by Step

RECALL:
(1) The complement of a set R is the set that contains the elements of the universal set U that are not in R.
(2) The symbol $\cap$ represents intersection of sets which lists down in a set the elements that are common to the given sets.
Use (1) above to obtain:
$R' = \left\{5, 6, 7, 8, 9, 10, 11, 12, 13\right\}$
Use (2) above to obtain:
$Q \cap R' = \left\{6, 8, 10, 12\right\}$
