Students will work with composite numbers to find their prime factorizations in exponent form. They will create factor trees and use division as a means to finding prime factors. Then students will use the handheld's factor command to quickly obtain the prime factorization in exponent form. Extensions are available at the end of the activity.

Students explore a geometric sequence that models the spread of the 2004 Mydoom virus. After finding a rule for the sequence, they apply it recursively to extend it and graph the resulting data as a scatter plot. Then they derive, evaluate, and graph an exponential function to model the data. The activity concludes by discussing the meaning of the constants a and b in the exponential function f(x) = abx.

This activity allows students to work independently to discover rules for working with exponents, such as the Power of a Power rule. Students also investigate the value of a power whose exponent is zero or negative. As an optional extension, students investigate the value of a power whose exponent is a fraction with a numerator of one.
