Explanation:

The test contains 10 questions, each one can be answered either with 'true' or with 'false' which means that for each question there are only 2 options.

We need to find the number of ways in which the test can be completed.

To answer the question we use the fundamental counting principle:

In this case, there are 2 ways to complete each question, therefore, we multiply that by the 10 questions that we have:


2*2*2*2*2*2*2*2*2*2

This can be simplified to


2^(10)

which is equal to:


2^(10)=\boxed{1024}

Answer:

1024
