## Lesson 23: Integer Exponents

** Description:**To motivate the convention for negative and zero exponents, the lesson begins by observing the halving pattern found in continuously decreasing the exponent of a power of two by 1. After an application looking at the formula for Body Mass Index calculation, power functions of the form f(x) = kx^p are introduced. Radiation Intensity application problems follow before pure algebraic manipulation of exponential expressions are presented. The lesson concludes with a review of scientific notation.
