Defines the roots of a number generally, the parts of a radical and radical expressions. Defines perfect and imperfect powers and demonstrates how to use the radical properties. Methods of extracting roots of perfect power radicands and more complicated expressions are explained. Rational exponents are introduced, demonstrating how to write radical expressions in both radical and exponential forms. How to write radical expressions in equivalent forms, rewrite radical fractions as fractions with rational denominators and how to rewrite radicals as radicals of a different order are covered. Finally, simplified radicals are defined, techniques to rewrite radicals in simplest form and combining radical expressions are discussed. 494 problems solved in detail, with explanations. Includes a topic-specific glossary, reference and index.
