Answer:
390625
Step-by-step explanation:
The questions are all independent -- the answer on one question does not limit the number of possible answers on another question.
The quiz has 5 choices for each question, so there are
[tex]5\times5\times5\times5\times5\times5\times5\times5[/tex] ways to answer the quiz questions.
Notice that this could be written [tex]5^8[/tex]. You could say that the number of ways to answer the questions is
[tex]number \, of \, choices^{number \, of \, questions}[/tex]
Use a calculator to find [tex]5^8[/tex]
