Slide1Introduction to RadicalsRadical Expressions Finding a root of a number is the inverse operation of raising a number to a power. This symbol is the radical or the radical sign index radical sign radicand The expression under the radical sign is the radicand. The index defines the root to be taken.
Slide2Square RootsIf a is a positive number, then is the positive square root of a and is the negative square root of a . A square root of any positive number has two roots – one is positive and the other is negative. Examples: non-real # Introduction to Radicals
