Power

An expression written with a base and an exponent or the value of such an expression
4^2 

Base

The number in a power that is used as a factor.
In 2^3, 2 is the base. 

Exponent

The number that indicates how many times the base in a power is used as a factor
In 2^3, 3 is the exponent 

Radicand

The expression under the radical sign
In ∛27, 27 is the radicand 

Index

In the radical √(n&x), which represents the nth root of x, n is the index. In the radical √x, the index is understood to be 2.
In ∛27, 3 is the index 

Rational Exponent

An exponent that can be expressed as m/n such that if m and n are integers, then b^(m/n)= √(n&b^m )=(〖√(n&b) )〗^m
In, 4^(3/2) 3/(2 ) is the rational exponent 

Radical function

A function whose rule contains a variable within a radical
f(x) = ∛x 

Square root function

A function whose rule contains a variable under a square root sign.
f(x)= √x 

Radical equation

An equation that contains a variable within a radical
2√(x+1)=14 

radical inequality

An inequality that contains a variable within a radical
√(x3)+ 2≤5 

Extraneous solution

A solution of a derived equation that is not a solution of the original equation
2 is an extraneous solution to √(x+18)=x2 

like radical terms

Radical terms having the same radicand and index
∛27and 4∛27 

domain

The set of all possible input values of a relation or function


range

The set of all possible output values of a relation or function


simplify

To perform all indicated operations
3∛8= 6
