Answer:
[tex]3.52 * 10^{13}[/tex]ways

Since 1 task can be assigned to 1 person, we can start by assigning people to the task. There are 15 different task, so at the first task there are 8 choices, at the 2nd task there are also 8 choices, and so on. There's also the fact that these tasks are all different.
Therefore the total number of way to assign 8 people to 15 tasks is
[tex]8^15 = 3.52 * 10^{13}[/tex] ways
