Final answer:
There are 390,625 ways a student can answer the questions on the test if every question is answered.
Step-by-step explanation:
To find the number of ways a student can answer the questions on the test, we need to consider that for each question, there are 5 possible answers. Since there are 8 questions on the test, we can use the multiplication principle to find the total number of ways:
Total number of ways = 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 = 5⁸ = 390,625 ways.
Therefore, there are 390,625 ways a student can answer the questions on the test if every question is answered.
