General purpose of this lecture is to present on Simplify Radicals. Here briefly focus on simplify square roots, and simplify radical expressions. A radical is also in simplest form when the radicand is not a fraction. Example: 33, for example, has no square factors. Its factors are 3· 11, neither of which is a square number. Therefore, radicals is in its simplest form. When working with the simplification of radicals you must remember some basic information about perfect square numbers.
