Answer:
1310720
Step-by-step explanation:
Given,
Total number of questions = 10,
Number of choices = 5,
If there are no two consecutive answers,
That is, if we have options a, b, c, d and e for each question,
Then, a could not be the answer of two consecutive questions,
We could pick 1 out of 5 answers for the first question and then for the remaining 9 questions we have only have 4 choices,
Hence, the total number of ways = 5 × 4 × 4 × 4 × 4 × 4 × 4 × 4 × 4 × 4
