A radical function is a type of function that contains a square root, cube root, or other root of a variable. For example, the function y = √x is a radical function.
Rational exponents are exponents that are fractions. For example, x^(2/3) is a rational exponent.
A binomial radical expression is an expression that contains two terms that are connected by a radical sign. For example, √(x + y) is a binomial radical expression.
