Important rules to simplify radical expressions and expressions with exponents are presented along with examples. index the number above the radical sign indicating the nth root. If no index is given, then the index is assumed to be 2 (2nd root, aka the square root). Radicals - The symbol $$\sqrt[n]{x}$$ used to indicate a root is called a radical and is therefore read "x radical n," or "the nth root of x." If you learn the rules for exponents and radicals, then your enjoyment of mathematics will surely increase! Radicals and exponents (also known as roots and powers) are two common — and oftentimes frustrating — elements of basic algebra.
