There is no difference between the values of them. However radicals are the notation used because they allow for higher roots.
The square root of 4 is 2
The cube root of 81 is 3
But there is no 'nice' name for say, the 34th root, or the .7th root. This is where the radical sign comes in. You can place whatever root you are taking above the 'V' part of the radical sign, and that makes equations easier to look at and work with.

A polynomial is an expression of various exponentials of a variable wich may or may nor have coefficients and constants. The coefficients may have a radical, square root, cube root etc, but not the variable. A radical expression is any expression involving square roots, cube roots, etc. These may have the variable inside the radical but do not have to have them. sq root (5) is a radical expression, so is sq root (x) 3x2 + 2x - 9 is a polynomial, so is x + sq root (5)
What square root property is essential to solve any radical equation involving square root?
The square root of 28 in simplified radical form is...2 * Square root of 7
Sqrt[5*radical(68)] = -6.4211 and +6.4211.
A "radical" equation is an equation in which at least one variable expression is stuck inside a radical, usually a square root. The "radical" in "radical equations" can be any root, whether a square root, a cube root, or some other root. Most of the examples in what follows use square roots as the radical, but (warning!) you should not be surprised to see an occasional cube root or fourth root in your homework or on a test.
