Answer
$125$
Work Step by Step
We are assigning each of three jobs to one of five different employees. There are 5 choices for assigning the first job, 5 choices for assigning the second job (since more than one job can be given to the same employee), and 5 choices for assigning the third job. By the multiplication principle on page 286, the total number of choices is $5*5*5=125$.
