    The first question can be answered in one of 4 ways. Likewise the second question can be answered in one of 4 ways. So there are 4*4 = 4² ways the first two questions can be answered.

    Extend that to all 10 questions and there are a total of 4¹⁰ = 1048576 different sets of answers to the test.
