Question

A multiple choice test contains 10 questions. There are four possible answers for each question.

(a) How many ways can a student complete the test if every question must be answered?

Answer 1

The number of ways a student can complete the test, with every question must be answered, is 4^10 = 1,048,576.

Step-by-step explanation:

The number of ways a student can complete the test, with every question must be answered, can be determined using the concept of permutations. Since there are four possible answers for each question, the number of ways to answer each question is 4. Since there are 10 questions in total, the total number of ways to complete the test is 4 to the power of 10, which can be written as 4^10 = 1,048,576.
