The answer is .04. The result will be one. When finding the value of negative exponents of fractions, you still change the fraction to its reciprocal. The opposite is true when the base is an improper fraction. The above can also be applied to negative exponents or irrational numbers.
Students can use the examples first and then explore with some possibilities of their own.
In this case, technology allows the student to quickly view their results to the examples. This allows them to focus on the concept they are exploring rather than getting bogged down in the tedious calculations they would have had to work through if technology were not available.
