Radical Form Math


Introduction to Radical form Math:

In mathematics subject there are so many chapters and so many topics are there. A radical is one of the important topics in that. A radical number is known as, which is the factor value of under the root symbol, and radical expression is containing a square root. Radical is denoted by the symbol of v (Sqrt).it has two forms, one is radical form, and other one is exponential form. Now we are going to see about radical form in math.

Radical Form Math:

Radical form is also called as Root form. it is nothing but to change the order of the exponential form into radical (root) form.

Important steps to remember how to change radical form:

Radical form into exponential form changed by to the power of exponent. For Example: 3v x = (x) 1/3 .
2.  Exponential form into radical form is change the exponent to under the radical. For example: (y) 1/2 = 2v y.

3.  Xn is called the nth root of x and is written as nv x or n Sqrt (x).

4.  If x and y are positive rational numbers and n is any rational exponent, Then xn * yn = (x * y) n. 

5.  If y = q Sqrt (x) or qv x = x 1/q then, x1/q is the exponential form and qv x or q Sqrt (x) is the radical form of x. (Where, q is the index of the radical, x is the radicand).

6.  If x and y are positive rational numbers and n is any rational exponent, Then xn * yn = (x * y) n.

Example Problems in Radical Form Math:

Radical to exponential form:

Example problem 1:

To change the given radical form into the exponential form 3v (11)

Solution:

Given: 3v (11)

= (11)1/3

The required exponential form is (11)1 / 3.

Exponential form to Radical form:

Example problem1:

To change the given exponential form into the radical form (17) - 1/2

Solution:

Given: (17) -1/2

= (17) - 1/2 = (1 / 17)1/2

The required radical form is 2v 1 / 17).

Example problem 2:

To change the given exponential form into the radical form (27 / 220) - 1/4

Solution:

Given: (27 / 220) -1/4

= (27 / 220) - 1/4 = (220 / 27)1/4

The required radical form is 4v (220 / 27).
