# Study Guide - Chapters 7-8

All problems are directly out of the odds in the textbook.

1. Simplify each expression as much as possible. Express all answers in terms of positive exponents. Assume that all variables represent positive real numbers (so that you don't have to worry about the square root of x squared being the absolute value of x). Write any complex numbers in standard a + bi form. 20 parts.
2. Solve the equations. 6 parts.
3. Solve the inequalities. 2 parts.
