Radical Form in Math

Introduction to radical form in math:

Radicals is a form of symbol which is used in the mathematics. It is shown that the radical  symbol as  root "v". The number inside the radical symbol which is called as the radicand of the radical value, for example if the given value is square root of `sqrtx` . The x is called as the radicand which is the number inside the radical symbol root "v". There are more number of rooting methods available depending upon the value we have. The roots are square root `sqrtx` , cube root `root(3)(x)` , Fourth root `root(4)(x)` this up to nth root `root(n)(x)` . Here we are going to see about the radical form in math in different methods and the solved example problems on it.

Understanding How do you Simplify Radicals is always challenging for me but thanks to all math help websites to help me out.

Radical form in math - Some Properties:

Radicals form - Representations:

Function `a^(1/n)` :

The radical exponent  `a^(1/n) = root(n)(a)`

If n has odd value then,

If a is positive value then the function  `a^(1/n)` is positive.

If a is negative value then the function `a^(1/n)` is negative.

If a is zero value then the function `a^(1/n)` is also zero

If n has even value then,

If a is positive value then the function `a^(1/n)` is positive.

If a is negative value then the function `a^(1/n)` is not a real number.

If a is zero value then the function`a^(1/n)` is also zero

Radical Expression:

`x^(1/n) = root(n)(x)`    it is n root of x value.

Relation between expression and Radical:

`(x^(1/n))^n`   is the relation between the expression and radical .

Radical Exponent of Product:

`root(n)(axxb) = (axxb)^(1/n) = root(n)(a) xx root(n)(b) = a^(1/n) xx b^(1/n) `

Radical for a quotient:

`root(n)(a/b) = (a/b)^(1/n) = root(n)(a)/root(n)(b) = a^(1/n)/b^(1/n)`

Radical of a fraction:

`msqrta^n = a^(n/m) `


Radical form in math - Example Problems:


Radical form in math -  Problem 1:

Solve the radical form for 16.

Solution:

Method 1: Finding the square root of 16 by long division method

_4__
2)16 (
16
0
The value for the `sqrt 16` is 4

Method 2:

`sqrt16` = `sqrt(4^2)`

=` (4^2)^2`

= `(4)^(2/2)`

= 4

Radical form in math - Problem 2:

Solve radical value for 435

Solution:

The root value 435 is nearly equal to the square values between 20 and 21, because 202 = 225 and 212 = 256

Step 1: Divide 435 by 20.

`435 / 20` = 21.75

Step 2: Take average for 21.75 and 20.

` (21.75+20)/2 ` = 20.87500

Step 3: Divide 255 by 16

`435/20.87500 ` =  20.8383234



Step 4: Take average for the 20.8383234 and 20.87500

`( 20.8383234 + 20.87500)/2` =  20.8566617

Step 5: Now check the above result by taking square

20.8566617 2 =  435.000337

This value is more or less equal to 435

If the value is not equal repeat the step 3 and step 4
